Andrew Kushnir b1d7b79ff4 fix(core): hardening attribute and property binding rules for <iframe> elements (#48029)
This commit updates the logic related to the attribute and property binding rules for <iframe> elements. There is a set of <iframe> attributes that may affect the behavior of an iframe and this change enforces that these attributes are only applied as static attributes, making sure that they are taken into account while creating an <iframe>.

If Angular detects that some of the security-sensitive attributes are applied as an attribute or property binding, it throws an error message, which contains the name of an attribute that is causing the problem and the name of a Component where an iframe is located.

BREAKING CHANGE:

Existing iframe usages may have security-sensitive attributes applied as an attribute or property binding in a template or via host bindings in a directive. Such usages would require an update to ensure compliance with the new stricter rules around iframe bindings.

Andrew Kushnir 92cf9fbebe fix(core): ViewContainerRef.createComponent should consult module injector when custom one is provided (#44966)
Before Ivy, it was only possible to call the `ViewContainerRef.createComponent` function with the ComponentFactory as the first argument. An instance of a `ComponentFactory` resolved via `ComponentFactoryResolver` contained a reference to an `NgModule` where the component is declared. As a result, the component maintained a DI connection with the module injector tree (by retrieving an instance of `NgModuleRef` internally), even when the custom injector was provided (we try to find a token in a custom injector first and consult module injector after that).

With Ivy, we expanded the `ViewContainerRef.createComponent` function API to support direct references to the Component classes without going through the factory resolution step. As a result, there was no connection to the NgModule that declares the component. Thus, if you provide a custom injector, this is the only injector that is taken into account.

This commit updates the logic for the factory-less case to try retrieving an instance of an `NgModuleRef` using the DI tree which `ViewContainerRef` belongs to. The `NgModuleRef` instance is then used to get a hold of a module injector tree. This brings the factory-less and factory-based logic to more consistent state.

Closes #44897.

Andrew Scott 5626b34264 fix(core): consistently use namespace short name rather than URI (#44766)
`Renderer2` APIs expect to be called with the namespace name rather than
the namespace URI. Rather than passing around the URI and having to
account for different calling contexts, this change consistently uses
the namespace short names.

Importantly, the URI was only used in `component_ref.ts` `create`
(because `getNamespace returned the URIs`) and `createElementNode` in
`node_manipulation.ts` (because `getNamespaceUri` also used the URIs).
In contrast, attributes would use the _short names instead of URIs_
(see `setUpAttributes` in `attrs_utils.ts`). These names are pulled
directly from the attribute, i.e. `xhtml:href` and not converted to URI.
This dichotomy is confusing and unnecessary. The change here aligns the two
approaches in order to provide consistently throughout the system.

This relates to #44766 because the `createElementNode` was calling the
`AnimationRenderer.createElement` which delegates to the
`ServerRenderer`, which in turn was only set up to expect short names.
As a result, the `NAMESPACE_URIS` lookup failed and `Domino` created
the `svg` as a regular `Element` which does not have a `styles`
property.

* `forwardRef` does not work with ES2015 and TypeScript's decorator

Paul Gschwendtner b23ce150d0 build: bundle spec files for saucelabs legacy job (#44281)
Bundle spec files similar to how it is done within the Angular
Components repo. This should simplify the setup and also speed
up the Saucelab job as only a single spec bundle would need to be
downloaded, compared to having to load hundreds of files through the
Saucelabs tunnel.

Also makes a couple of tests more robust with the emulators/and accounts
for ES2015 test runner changes. The tests should be less reluctant to
such build process changes.

Note for reviewers: Some imports have been simplified here. This work
came from Joey's original WIP for this. It's unclear to me whether this
is still needed, but it sounded like this was necessary for the ESBuild
bundling to work. I have robusted the module resolution plugin though,
so I doubt it's still needed. At the same time though: Not worth
reverting/trying as these changes are nice to have anyway!

JoostK 4f8eaac7ff fix(core): do not use Function constructors in development mode to avoid CSP violations (#43587)
This commit removes the dynamic creation of named arrays for internal
runtime storage arrays as they may cause CSP violations in development
mode,  when an application's CSP configuration does not include
`unsafe-eval`.

Named arrays for view data can still be enabled in development mode
using the `ngDevMode=namedConstructors` query parameter when loading the
application.

The usage of native class syntax for named arrays does not have the
desired effect when the code is downleveled to ES5. Since ES5 targets
are becoming increasingly more rare this is considered less of a problem
than the CSP violation.

JoostK b249e24979 fix(compiler): generate correct code for safe method calls (#44088)
When a safe method call such as `person?.getName()` is used, the
compiler would generate invalid code if the argument list also contained
a safe method call. For example, the following code:

```
person?.getName(config?.get('title').enabled)
```

would generate

```
let tmp;
ctx.person == null ? null : ctx.person.getName((tmp = tmp) == null ?
null : tmp.enabled)
```

Notice how the call to `config.get('title')` has completely disappeared,
with `(tmp = tmp)` having taken its place.

The issue occurred due to how the argument list would be converted
from expression AST to output AST twice. First, the outer safe method
call would first convert its arguments list. This resulted in a
temporary being allocated for `config.get('title')`, which was stored in
the internal `_resultMap`. Only after the argument list has been
converted would the outer safe method call realize that it should be
guarded by a safe access of `person`, entering the `convertSafeAccess`
procedure to convert itself. This would convert the argument list once
again, but this time the `_resultMap` would already contain the
temporary `tmp` for `config?.get('title')`. Consequently, the safe
method in the argument list would be emitted as `tmp`.

This commit fixes the issue by ensuring that nodes are only converted
once.

With Ivy it's possible to create a `ComponentFactory` instance based on the generated Component def, thus the `ViewContainerRef.createComponent` can accept a Component instance and create a factory inside, rather than requiring additional complexity of creating a ComponentFactory outside (by invoking `ComponentFactoryResolver`).

This should simplify the API that is used for creating components dynamically.

Kristiyan Kostadinov 2028c3933f refactor(compiler): combine call ASTs (#42882)
Currently the compiler has three different classes to represent a "call to something":
1. `MethodCall` - `foo.bar()`
2. `SafeMethodCall` - `foo?.bar()`.
3. `FunctionCall` - Any calls that don't fit into the first two classes. E.g. `foo.bar()()`.

There are a few problems with this approach:
1. It is inconistent with the TypeScript AST which only has one node: `CallExpression`.
2. It means that we have to maintain more code, because the various parts of the compiler need to know about three node types.
3. It doesn't allow us to easily implement some new JS features like safe calls (e.g. `foo.bar?.())`).

These changes rework the compiler so that it produces only one node: `Call`. The new node behaves  similarly to the TypeScript `CallExpression` whose `receiver` can be any expression.

There was a similar situation in the output AST where we had an `InvokeMethodExpression` and `InvokeFunctionExpression`. I've combined both of them into `InvokeFunctionExpression`.

Kristiyan Kostadinov 8628826535 fix(core): incorrect error reported when trying to re-create view which had an error during creation (#43005)
Currently if a view throws an error during creation mode, we mark it as `incompleteFirstPass` so that we can try to recover later. The recovery is only possible inside component views.

The problem is that when this was introduced, I forgot to flip the `firstCreatePass` when an error is thrown which meant that calling `renderView` on the same component again is allowed. It will eventually hit an assertion which can be confusing for the end user. This issue only manifests itself when rendering views "manually" through `ViewContainerRef` (e.g. using `NgIf`).

These changes flip the `firstCreatePass` back to false on errors so that trying to re-render the same view will throw an error which is consistent to the one that broke the view during creation.

Kristiyan Kostadinov 873229f24b feat(core): add opt-in test module teardown configuration (#42566)
We currently have two long-standing issues related to how `TestBed` tests are torn down:
1. The dynamically-created test module isn't going to be destroyed, preventing the `ngOnDestroy` hooks on providers from running and keeping the component `style` nodes in the DOM.
2. The test root elements aren't going to be removed from the DOM. Instead, they will be removed whenever another test component is created.

By themselves, these issues are easy to resolve, but given how long they've been around, there are a lot of unit tests out there that depend on the broken behavior.

These changes address the issues by introducing APIs that allow users to opt into the correct test teardown behavior either at the application level via `TestBed.initTestEnvironment` or the test suite level via `TestBed.configureTestingModule`.

At the moment, the new teardown behavior is opt-in, but the idea is that we'll eventually make it opt-out before removing the configuration altogether.

Kristiyan Kostadinov 4bc5b4d93b fix(core): global listeners not being bound on non-node host elements (#42014)
We skip event listeners on non-element host nodes (e.g. `ng-container` or `ng-element`), because they don't map to a DOM node so there's nothing to bind the event to. The problem is that this also prevents listeners bound to global targets from being bound.

These changes add an extra condition to allow for the event to be bound if it has a custom event target resolver.

Fixes #14191.

Pete Bacon Darwin 9b4b281c52 fix(core): handle multiple i18n attributes with expression bindings (#41882)
When there are multiple attributes that are marked for i18n translation,
which contain expression bindings, we were generating i18n update op-codes
that did not accurately map to the correct value to be bound in the lView.
Each attribute's bindings were relative to the start of the lView first
attributes values rather than to their own.

This fix passes the current binding index to `generateBindingUpdateOpCodes()`
when processing i18n attributes to account for this.

Fixes #41869

Kristiyan Kostadinov 36c7bebe40 test(core): make tests more resilient to header offset changes (#41883)
Updates some tests where values related to the `HEADER_OFFSET` are hardcoded, causing them to break when the offset is updated. This comes up once in a while during refactorings and these changes should save us some time in the future.

Kristiyan Kostadinov 18b33e79d3 perf(core): avoid storing LView in __ngContext__ (#41358)
Currently we save a reference to an `LView` on most DOM nodes created by Angular either by saving
the `LView` directly in the `__ngContext__` or by saving the `LContext` which has a reference to
the `LView`. This can be a problem if the DOM node is retained in memory, because the `LView` has
references to all of the child nodes of the view, as well as other internal data structures.

Previously we tried to resolve the issue by clearing the `__ngContext__` when a node is removed
(see https://github.com/angular/angular/pull/36011), but we decided not to proceeed, because it can
slow down destruction due to a megamorphic write.

These changes aim to address the issue while reducing the performance impact by assigning a unique
ID when an `LView` is created and adding it to `__ngContext__`. All active views are tracked in
a map where their unique ID is used as the key. We don't need to worry about leaks within that map,
because `LView`s are an internal data structure and we have complete control over when they are
created and destroyed.

Fixes #41047.
