Currently, when importing `BrowserAnimationsModule`, Angular provides
`AnimationRendererFactory` as the `RendererFactory2`. The `AnimationRendererFactory`
relies on the `AnimationEngine`. The `AnimationEngine` may be created earlier than the
`ApplicationRef` (e.g. if it's requested within the `APP_INITIALIZER` before the `ApplicationRef`
is created). This means that Angular will add the `AnimationEngine` to `R3Injector.onDestroy`
before the `ApplicationRef`. The `R3Injector` will call `ngOnDestroy()` on the `AnimationEngine`
before the `ApplicationRef`, which means the `flush()` will be called earlier before views are destroyed.

This change separates the router initializer into different providers.
While it does not actually change the tree-shakeablity or the public
API, it does move us towards a world that _could_ do this. That is,
instead of `initialNavigation: 'disabled'`, users could use
`provideDisabledInitialNavigation` in the `bootstrapApplication` call
and none of the code for `initialNavigation: 'enabledBlocking'` would be
included in the application.

Extracting preloading to a provider moves us towards
thinking about a world where `ExtraOptions` doesn't exist to control
behaviors that are opt-in/opt-out. Instead, these behaviors could be
controlled by the presence (or lackthereof) of the providers which has
the functionality. This is relevant to a world in which we no longer
have the `RouterModule` but instead have something like `provideRouter`
where the features are tree-shakeable.
This change _does not_ make the `RouterPreloader` tree-shakeable inside
`RouterModule.forRoot` because the compiler cannot statically determine
whether it's needed. However, in the `provideRouter` world without
`forRoot`, preloading could be exposed through the provider function
instead, making the `RouterPreloader` and `PreloadingStrategy`
implementations tree-shakeable for those that don't use it (which is the
default - no preloading).

During JIT compilation of standalone components the compiler did not deduplicate
declarations in the imports array, unlike the AOT compiler. This may result in
runtime errors during directive matching, when the same component is found
multiple times resulting in NG0300, for example:
> NG0300: Multiple components match node with tagname mat-form-field: MatFormField and MatFormField.
This commit fixes the issue by deduplicating imports in the JIT compiler.

The `Observable` chain is currenlty the most straightforward way to
handle navigation cancellations where we ensure that the cancelled
navigation does not continue to be processed. Until we design and
implement an alternative way to accomplish equivalent functionality,
we need to maintain the `Observable` chain wherever we might execute
user code. One reason for this isthat user code may contain redirects so we do not
want to execute those redirects if the navigation was already cancelled.

Consider the case in which `FormBuilder` is used to construct a group with an optional field:
```
const controls = { name: fb.control('') };
const foo: FormGroup<{
name: FormControl<string | null>;
address?: FormControl<string | null>;
}> = fb.group<{
name: FormControl<string | null>;
address?: FormControl<string | null>;
}>(controls);
```
Today, with fully strict TypeScript settings, the above will not compile:
```
Types of property 'controls' are incompatible.
Type '{ name: FormControl<string | null>; address?: FormControl<FormGroup<SubFormControls> | null | undefined> | undefined; }' is not assignable to type '{ name: FormControl<string | null>; address?: FormGroup<SubFormControls> | undefined; }'.
```
Notice that the `fb.group(...)` is calculating the following type for address: `address?: FormControl<FormGroup<string|null>`. This is clearly wrong -- an extraneous `FormControl` has been added!
This is coming from the calculation of the result type of `fb.group(...)`. In the type definition, if we cannot detect the outer control type, [we assume it's just an unwrapped value, and automatically wrap it in `FormControl`](https://github.com/angular/angular/blob/14.0.0/packages/forms/src/form_builder.ts#L66).
Because the optional `{address?: FormControl<string|null>}` implicitly makes the RHS have type `FormControl<string|null>|undefined`, [the relevant condition is not satisfied](https://github.com/angular/angular/blob/14.0.0/packages/forms/src/form_builder.ts#L55). In particular, the condition expects just `FormGroup<T>`, not `FormGroup<T>|undefined`. So we assume `T` is a value type, and it gets wrapped with `FormControl`.
The solution is to add the cases where `undefined` is included in the union type when detecting which control `T` is (if any).

Angular generally supports cycles between components in the same NgModule.
We have a mechanism of moving the component scope declaration into the
NgModule file in this case. This ensures that Angular never itself
introduces an import which creates a cycle.
What happens if the cycle already exists in the user's program, though, is a
bit different. In these cases, the "correct" emit for Angular is to generate
the component scope (whether direct or remote) inside of a closure, to
prevent evaluating the scope's references until module evaluation is
complete and all cyclic imports have been resolved. We don't want to do this
for *all* scopes because the code size cost of emitting a function wrapper
is non-zero.
In this fix, we take the presence of a `forwardRef` in a component's
`imports` or in an NgModule `declarations` or `imports` as a sign that
component scopes emitted into those files need to be protected against
cyclic references. In a future commit, we may introduce a warning or error
if cyclic imports are not protected behind `forwardRef` in these cases, but
this will take some time to implement.

This exposes a new function from the router public API that allows
developers to create a `UrlTree` from _any_ `ActivatedRouteSnapshot`.
The current Router APIs only support creating a `UrlTree` from an
`ActivatedRoute` which is both active _and_ materially appears in the
`UrlTree` (it cannot be an empty path named outlet). This is because the
implementation of the current way of creating a `UrlTree` attempts to
look up the `UrlSegment` of the `ActivatedRoute` in the currently active
`UrlTree` of the router. When this doesn't work, the `UrlTree` creation
fails.
Note that this API does not replace the current one. That would actually be a
breaking change but should be done at some point in the future (v15). That is,
`router.navigate` should call this new function. At that point, we can
remove `_lastPathIndex`, `_urlSegment`, and `_correctedPathIndex` from
the `ActivatedRoute`, along with all of the logic associated with
determining what those should be. In addition, this would unblock a fix
for #26081 because the `applyRedirects` and `recognize` operations
could be combined into one. Overall, this would simplify logic in the router
and reduce code size. It also exposes core routing capabilities as a helper function
which were previously private API, which is a necessary step towards #42953.
As a stress test for this new function, it _was_ swapped in as the
default for `UrlTree` creation in #45859 and tested internally. The
results indicate that this function behaves correctly.

Currently for cases when an unknown structural directive is applied to `<ng-template>`s, an error message thrown by the framework doesn't contain a tag name, for example:
```
NG0303: Can't bind to 'unknownDir' since it isn't a known property of 'null'.
```
The underlying reason is that the tag name for the `<ng-template>` is not produced (`null` is useed as a value) by the compiler in case of inline templates and runtime logic relies on this effect.
This commit handles this situation when an error message is thrown, as the fastest way to improve the error message. More refactoring would be needed to avoid relying on the mentioned effect at runtime.

Currently, the `Router` will create the `EnvironmentInjector` for a
`Route` with `providers` as soon as it _attempts_ to match segments to

injector once we have confirmed that the `Route` matches. Note that this
will include partial matches where the final navigation still fails with
a "cannot match any routes to segment" error. We need to maintain the
injector hierarchy so we still need to create parent injectors before
descending into the child routes and determining if there is a full
match or just a partial one.

The `inject()` function was introduced with Ivy to support imperative
injection in factory/constructor contexts, such as directive or service
constructors as well as factory functions defined in `@Injectable` or
`InjectionToken`. However, `inject()` in a component/directive constructor
did not work due to a flaw in the logic for creating the internal factory
for components/directives.
The original intention of this logic was to keep `ɵɵdirectiveInject` tree-
shakable for applications which don't use any component-level DI. However,
this breaks the `inject()` functionality for component/directive
constructors.
This commit fixes that issue and adds tests for all the various cases in
which `inject()` should function. As a result `ɵɵdirectiveInject` is no
longer tree-shakable, but that's totally acceptable as any application that
uses `*ngIf` or `*ngFor` already contains this function. It's possible to
change how `inject()` works to restore this tree-shakability if needed.
