Cleans up all the tests that had to declare a separate module in order to pass in `entryComponents` when creating components dynamically. This covers almost all of the `entryComponents` usages, except for a few which I've left for now, because they're testing some of the existing leftover `entryComponents` logic in core.

This commit removes most tests that were designated as only covering View
Engine code. It also removes tag filters from CI and local commands to run
tests.
In a few cases (such as with the packages/compiler tests), this tag was
improperly applied, and certain test cases have been added back running in
Ivy mode.
This commit also empties `@angular/compiler/testing` as it is no longer
necessary (this is safe since compiler packages are not public API). It can
be deleted in the future.

The TestBed APIs to override metadata would crash when the metadata
contained objects with cyclic references. Metadata overrides use the
JSON serialized representation of a value to compare objects, which
throws an error if the value has cyclic references. This commit avoids
the error by replacing multiple occurrences of the same object using
a unique string representation for the object.

When a partially compiled component or directive is "linked" in JIT mode, the body
of its declaration is evaluated by the JavaScript runtime. If a class is referenced
in a query (e.g. `ViewQuery` or `ContentQuery`) but its definition is later in the
file, then the reference must be wrapped in a `forwardRef()` call.
Previously, query predicates were not wrapped correctly in partial declarations
causing the code to crash at runtime. In AOT mode, this code is never evaluated
but instead transformed as part of the build, so this bug did not become apparent
until Angular Material started running JIT mode tests on its distributable output.
This change fixes this problem by noting when queries are wrapped in `forwardRef()`
calls and ensuring that this gets passed through to partial compilation declarations
and then suitably stripped during linking.

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.

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.

NgModule factories are obsolete with Ivy and most of the operations can already be performed with NgModule classes without retreieving corresponding factories. NgModule factories were useful to generate an `NgModuleRef` (via `NgModuleFactory.create` method). This commit adds a new function to create an instance of the `NgModuleRef` class without having the need to create a factory first.

This commit adds a new function called `getNgModuleById` to the public API surface of the framework. The `getNgModuleById` function allows to retrieve loaded NgModule class by id (specified via `@NgModule.id`). The function is a replacement for the `getModuleFactory` function.
DEPRECATION:
The `getModuleFactory` function is deprecated in favor of the `getNgModuleById` one. With Ivy it's possible to work with NgModule classes directly, without retrieving corresponding factories, so the `getNgModuleById` should be used instead.

For APF v13, terser has been updated to v5, and the prodmode output
has changed from ES2015 to ES2020. This results in some changes in
the symbol extractor test. Here are the two causes of changes:
* As said in the previous commit, Terser drops the initializer for
variables which are set to `undefined`. We have updated the symbol
extractor to always capture such declarations w/o initializer now.
This means that a couple of declarations that a couple of new
symbols are captured now. These previously didn't have an initializer
even without Terser, and just didn't show up before.
* Terser changed its inline mechanism for functions that recursively
call themselves. Such functions are no longer inlined and therefore
show up in goldens now.

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.
DEPRECATION:
Angular no longer requires component factories to dynamically create components. The factory-based signature of the `ViewContainerRef.createComponent` function is deprecated in favor of a different signature that allows passing component classes instead.

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`.

The current behavior of `routerLink` for `null` and `undefined` inputs is to treat
the input the same as `[]`. This creates several unresolvable issues with
correctly disabling the links because `commands = []` does _not_ behave the same
as disabling a link. Instead, it navigates to the current page, but will also
clear any fragment and/or query params.
The new behavior of the `routerLink` input will be to completely disable navigation
for `null` and `undefined` inputs. For HTML Anchor elements, this will also mean
removing the `href` attribute.
Fixes#21457Fixes#13980Fixes#31154
BREAKING CHANGE:
Previously `null` and `undefined` inputs for `routerLink` were
equaivalent to empty string and there was no way to disable the link's
navigation.
In addition, the `href` is changed from a property `HostBinding()` to an
attribute binding (`HostBinding('attr.href')`). The effect of this
change is that `DebugElement.properties['href']` will now return the
`href` value returned by the native element which will be the full URL
rather than the internal value of the `RouterLink` `href` property.

The management of `browserUrlTree` currently has several problems with
correctly tracking the actual state of the browser.
This change makes the Router eagerly update the `browserUrlTree` when
handling navigations triggered by browser events (i.e., not 'imperative'). This
is because with those types of navigations, the browser URL bar is
_already_ updated. If we do not update the internal tracking of the
`browserUrlTree`, we will be out of sync with the real URL if the
navigation is rejected.
It would be best if we could remove `browserUrlTree` completely, but doing that
would require a lot more investigation and is blocked by #27059 because
the SpyLocation used in tests does not emulate real browser behavior.

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.

If a decorator or partial declaration has not been AOT compiled, then
the compiler is needed at runtime to be able to JIT compile the code.
However, it may occur that the compiler is not available, if it has not

case did not provide insight into which class requested compilation, nor
did it differentiate between decorators vs. partial declarations.

message for partial declarations. This should help a developer better
understand why the error occurs and what can be done to resolve it.

When using `TestBed.overrideComponent`, the overridden component would
incorrectly lose access to its NgModule's declaration scope if the
NgModule had been imported into the testing NgModule as a
`ModuleWithProviders`, e.g. using a `forRoot` call.
The issue occurred as the `TestBed` compiler did not consider NgModules
that had been imported as a `ModuleWithProviders` when associating
NgModules with component overrides. This caused the overridden component
to be compiled standalone, meaning that it does not have access to
its NgModule's declarations. This commit extends the logic for
traversing the NgModule graph to also consider `ModuleWithProviders`
imports.
