This commit updates the `NgLocalization` token to become tree-shakable (vs using a direct reference to that token in the `providers` section of the `CommonModule`). The `NgLocalization` token is used for apps that use i18n and for other apps it would be excluded from the bundle.

model.ts is currently extremely large. This is the first step in an attempt to refactor it to be more easily navigable and reviewable. This commit breaks up `model.ts` into the following new files:
* `model/abstract_model.ts`: The remainder of the model, including the `AbstractControl` base class and helper functions which are used throughout.
* `model/form_control.ts`: `FormControl`, `FormControlOptions`, and helpers, plus the constructor and untyped friends.
* `model/form_array.ts`: `FormArray` and untyped friends.
* `model/form_group.ts`: `FormGroup` and untyped friends.
This first phase is a purely mechanical code move. There is no new code at all, and no interfaces have been separated.

Zone.js supports the google closure compiler in the advance optimization mode,
to prevent closure compiler modify the `onProperty` name such as `Element.prototype.onclick`,
Zone.js implements the `onProperty` patch logic by declaring all the
event names in the source code, this increases the bundle size and also require
updating the event names array to keep the information updated.
Now google closure compiler has the required event names defined in the built-in
externs files, so zone.js can use more simple implementation and decrease the bundle size
of zone.js (about 4k).

The router used to wait for the resolvers to complete and take the last
value. The changes here take only the first
emitted value of every resolver and proceed the navigation. This matches
how other guards work in the `Router` code.
Resolves https://github.com/angular/angular/issues/44643
BREAKING CHANGE: Previously, resolvers were waiting to be completed
before proceeding with the navigation and the Router would take the last
value emitted from the resolver.
The router now takes only the first emitted value by the resolvers
and then proceeds with navigation. This is now consistent with `Observables`
returned by other guards: only the first value is used.

Currently, there is a freestanding `getRawValue` function which examines the type of the control. This is an issue for refactoring `model.ts` because it creates unnecessary dependencies between the `AbstractControl` classes. It is cleaner to simply add this method to the model hierarchy and call it directly, and will ease upcoming refactoring.

Adds support for passing in an optional injector when creating an embedded view through `ViewContainerRef.createEmbeddedView` and `TemplateRef.createEmbeddedView`. The injector allows for the DI behavior to be customized within the specific template.

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.

to find the one that's the closest ancestor for a given host element. An

an optimization where the closest namespace is found by traversing up from

`AsyncTestZoneSpec` triggers jasmine `done()` function multiple times
and causes warning
```
An asynchronous function called its 'done' callback more than once. This is a bug in the spec, beforeAll, beforeEach, afterAll, or afterEach function in question. This will be treated as an error in a future version. See<https://jasmine.github.io/tutorials/upgrading_to_Jasmine_4.0#deprecations-due-to-calling-done-multiple-times> for more information
```
The reproduce case will be running some `Zone.run()` inside
`waitForAsync()`.
```
it('multiple done', waitForAsync(() => {
Zone.current.run(() => {});
Zone.current.run(() => {});
}));
```
The reason the `done()` is called in the `onInvoke()` hook is to handle
the case that the testBody is totally sync, but we should only do this
check for the entry function not for all `Zone.run()` scenario.
Another issue is if we run nested zone inside `waitForAsync()`, the
`onHasTask()` hook will be triggered multiple times, and cause `done()`
be triggered multiple times, so we need to only trigger the `done()`
when the zone is `AsyncTestZone`.
PR Close#45025
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.

In templates with several levels of nested nodes, it's common for several `elementStart`/`elementEnd` instructions to show up in a row which can be optimized away.
These changes add chaining support for `elementStart`, `elementEnd`, `elementContainerStart` and `elementContainerEnd` to shave off some bytes when possible.
PR Close#44994
Previously the logic for generating chained instructions was somewhat rigid, because we had to collect all of the calls ahead of time and then call one of the chained instruction helpers. This doesn't work for something like `elementStart`, because we have to descend into other elements that could add to the chain.
These changes refactor the code so that we collect the list of instructions in a flat array and we do the chaining only once at the end when we have the entire instruction set for the code block.
The new approach has the advantage of being (almost) entirely configuration-based via the `CHAINABLE_INSTRUCTIONS` array and being more flexible in allowing us to chain instructions that span across elements.
