These changes combine #41358 and #41894.
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.

The prior approach would consider all existing namespaces from back to front
to find the one that's the closest ancestor for a given host element. An
expensive `contains` operation was used which needed to traverse all the
way up the document root _for each existing namespace_. This commit implements
an optimization where the closest namespace is found by traversing up from
the host element, avoiding repeated DOM traversal.

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.

This commit provides a service, `PageTitleStrategy` for setting
the document page title after a successful router navigation.
Users can provide custom strategies by extending `TitleStrategy` and
adding a provider which overrides it.
The strategy takes advantage of the pre-existing `data` and `resolve` concepts
in the Router implementation:
We can copy the `Route.title` into `data`/`resolve` in a
non-breaking way by using a `symbol` as the key. This ensures that we
do not have any collisions with pre-existing property names. By using
`data` and `resolve`, we do not have to add anything more to
the router navigation pipeline to support this feature.

When running tests with code coverage using Istanbul, the code is
instrumented with coverage reporting statements. These statements are
also inserted into synthesized constructors, preventing Angular from
properly recognizing them as synthesized constructor.
This commit changes the regex to detect synthesized constructors to allow
for statements within the constructor before the `super(...arguments);`
call. This is limited to code that does not contain a `}`, but this
is sufficient to support Istanbul's coverage instrumentation statements.
The tests have been extended with an input file that is being
instrumented using `babel-plugin-istanbul` for both ES2015 and ES5
targets, in order to verify that the approach works for real-world
usages.

`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.

when reordering a list with animations the list items lose their current
triggers values, that is because the reordering of an item is implemented
as follows (_note:_ the following implementation has been added in PR #23534)
- the item is removed and marked _setForRemoval_
- the item is re-inserted, and the _setForRemoval_ is changed to _setForMove_
- the player set for animating the removal is destroyed when _setForMove_ is detected
the above steps allow the element not to be animated and to keep its styling but the
triggers values get lost since the removal transition/player has already been initialized,
so this change adds a _previousTriggersValues_ map in the _REMOVAL_FLAG_ field in order to
restore the triggers values if/when the removal turns out to be a move, changing the above steps to:
- the item is removed and marked setForRemoval __and its current triggers values are saved as well__
- the item is re-inserted, and the setForRemoval is changed to setForMove
- the player set for animating the removal is destroyed when setForMove is detected __and the
trigger values are re-applied in the engine's statesByElement map__

This commit moves some logic to make the location of runtime error codes consistent across packages. Now all error codes are located in `packages/core/src/errors.ts` file.
PR Close#44398
This commit updates the code around the `RuntimeError` class to make it more reusable between packages (currently it's only usable inside the `core` package). Specifically:
- the error formatting logic was updated to handle cases when there is no error message provided
- there is no special Set that contains a set of error codes for which we have guides on angular.io. Instead, this is now encoded into the error code itself (making such codes negative integers). Having a separate Set makes it non-tree-shakable, which we want to avoid.
This change should allow to employ the `RuntimeError` class in other packages to further standardize this subsystem and make the errors thrown by the framework consistent.
As a part of the refactoring, the `common` package code was also updated to follow the same logic as `core`, since the `RuntimeError` class was used there as well.

Updates the acceptance core tests to work with ES2015 devmode output.
There were two issues surfacing:
* The NodeJS test execution failed because Domino does not handle
destructuring syntax properly. This is because `Node.children` is not
an iterable.
* `forwardRef` does not work with ES2015 and TypeScript's decorator
downlevel emit. This is a known limitation we work around in Angular
applications by either compiling tests with the Angular compiler, or
by running a custom decorator downlevel transform (like in the CLI).

The `ng_rollup_bundle` rule has been replaced with a new rule called
`app_bundle`. This rule replicates the Angular v13 optimization
pipeline in the CLI, so that we can get better benchmarking results.
Also the rule is much simpler to maintain as it relies on ESbuild.
The old `ng_rollup_bundle` rule did rely on e.g. build-optimizer that no
longer has an effect on v13 Angular packages, so technically size
tests/symbol tests were no longer as correct as they were before. This
commit fixes that.
A couple of different changes and their explanation:
* Language-service will no longer use the benchmark rule for creating
its NPM bundles! It will use plain `rollup_bundle`. ESBuild would have
been nice but the language-service relies on AMD that ESBuild cannot
generate (yet?)
* Service-worker ngsw-worker.js file was generated using the benchmark
bundle rule. This is wrong. We will use a simple ESbuild rule in the
future. The output is more predictable that way, and we can have a
clear use of the benchmark bundle rule..
* A couple of benchmarks in `modules/` had to be updated to use e.g.
`initTableUtils` calls. This is done because with the new rule, all
files except for the entry-point are considered side-effect free. The
utilities for benchmarks relied on side-effects in some
transitively-loaded file (bad practice anyway IMO). We are now
initializing the utilities using a proper init function that is
exported...

* The `TransitionAnimationEngine` had a fallback where it would store classes directly on a node if it doesn't have a `classList`. Presumably this is to support old browsers or if an animation is set on something like `ng-container`. This information was never used for anything since `containsClass` was never called. These changes simplify the logic to just a null check.
* Deprecates the `AnimationDriver.matchesElement` method, because it was only used in one place which can be replaced with `classList.contains`. We can't remove the method completely, because `AnimationDriver` is a public API. We also can't turn it into a method on the base class in order to remove it from the sub-classes, because it can break apps using `noImplicitOverride` while extending `AnimationDriver`.

This commit makes several changes to the implementation of `NgForOf` to
reduce its code size in production builds:
1. The tailor-made message for an unsupported differ is fully
tree-shaken in production builds, in favor of the exception from the
differ factory itself.
2. The private `_perViewChange` method was changed into a free-standing
function, to allow its name to be minimized.
3. The need for an intermediate `RecordViewTuple` was avoided by
applying the operation in-place, instead of collecting all insertions
into a buffer first. This is safe as the `_perViewChange` operation
that used to be done on each `RecordViewTuple` is entirely local to
the tuple itself. Hence, it is invariant to execution ordering which
means that the `_perViewChange` can be executed directly during the
`forEachOperation` loop.

Fixes an issue where destroy hooks are not set up for `useClass` providers
that rely on `forwardRef` for passing the actual class reference.
Currently the destroy hooks are not captured because forward refs are
not resolved for class providers. In ES2015+ this issue becomes even
more critical if arrow-functions are used for
e.g. `useClass: () => forwardRef(..)`.
This is because arrow functions do not have a prototype, unlike in ES5
where the function assigned to `useClass` would always have a prototype.
In ES2015+ a runtime exception as followed is returned (and doesn't give
any useful indication of the forwardRef issue):

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!
