Related to #51131, this change ensures that the router navigation exits
the current event loop before rendering the route when the view transition
feature is enabled, when the browser does not support view transitions.

Using `setTimeout` to delay scrolling can result in scrolling in the
next frame and cause noticeable flicker. This commit scrolls as soon as
the next render happens (or in `setTimeout` if a render does not happen
before then).

`RouterOutlet` uses a unique injector logic that returns a value that correspond to the `ActivatedRoute` token dynamically. This logic breaks when a component/directive/pipe that injects the `ActivatedRoute` is located within a `@defer` block, because defer creates an `EnvironmentInjector` instance, which doesn't have that dynamic logic.
We've added some special handling of the `OutletInjector` in one of the previous commits, but it was incomplete and it was not covering cases when different routes use the same component. This commit updates defer logic to re-establish this dynamic behavior for `ActivatedRoute` by creating an instance of the `OutletInjector` when a parent injector was also an instance of `OutletInjector`.
This fix is a short-term solution and longer term we should find a way to achieve the dynamic behavior that Router relies on, but without adding a special case logic into defer.
Resolves#54864.

This commit updates the `@defer` logic to establish proper injector resolution order. More specifically:
- Makes node injectors to be inspected first, similar to how it happens when `@defer` block is not used.
- Adds extra handling for the Router's `OutletInjector`, until we replace it with an `EnvironmentInjector`.

Previously, `RouterLinkActive` would only add or remove the active classes when
its active state changed. This means that if you accidentally add one of
the active classes to the static class attribute, it won't get removed
until the link becomes active and then deactives (because the class is
added at creation time and never removed until the `RouterLinkActive`
state changes from active to inactive).

This refactor makes it easier to update the return types of guards.
Rather than having to track what types guards can return, which may
change with new features over time, `MaybeAsync<GuardResult>` can be

This is a follow up to https://github.com/angular/angular/commit/5c1d4410298e20cb03d7a1ddf7931538b6a181b4
which added the `info` property to navigation requests. `RouterLink` now
supports passing that transient navigation info to the navigation
request.
This info object can be anything and doesn't have to be serializable.
One use-case might be for passing the element that was clicked. This
might be useful for something like view transitions. In the "animating
with javascript" example from the blog (https://stackblitz.com/edit/stackblitz-starters-cklnkm)
those links could have done this instead of needing to create a separate
directive that tracks clicks.

Use of the `SpyLocation` is problematic because it prevents location
APIs from reaching the platform level (`PlatformLocation`) and
`PathLocationStrategy`. This makes it difficult to test interactions
with those providers, including the ability to use the `Navigation` API,
which will live at the platform level.

The InitialRenderPendingTasks currently attempts to only contribute to
ApplicationRef stableness one time to support SSR. This isn't actually
how the switchMap works in reality. This commit updates
the isStable observable to be more clear that it's always a combination
of the zone stableness and pending tasks.
In addition, this commit renames the service to just be PendingTasks
because it doesn't directly relate to rendering. While the purpose is
to track things that might cause rendering to happen, we don't know if the
tasks will affect rendering at all.

The version of rxjs used to build the repository has been updated to v7.
This required only minimal changes to the code. Most of which were type
related only due to more strict types in v7. The behavior in those cases
was left intact. The most common type related change was to handle the
possibility of `undefined` with `toPromise` which was always possible with
v6 but the types did not reflect the runtime behavior. The one change that
was not type related was to provide a parameter value to the `defaultIfEmpty`
operator. It no longer defaults to a value of `null` if no default is provided.
To provide the same behavior the value of `null` is now passed to the operator.

Prior to this commit when a route is not matched and the application was running in production mode an `[Error]: NG04002` was logged in the console. This however, is not actionable when the application is running on the server where there can be multiple pages being rendered at the same time.
Now we change this to also log the route example: `[Error]: NG04002: 'products/Jeep'`.

This commit adds a property to the navigation options to allow
developers to provide transient navigation info that is available for
the duration of the navigation. This information can be retrieved at any
time with `Router.getCurrentNavigation()!.extras.info`. Previously,
developers were forced to either create a service to hold information
like this or put it on the `state` object, which gets persisted to the
session history.
This feature was partially motivated by the [Navigation API](https://github.com/WICG/navigation-api#example-using-info)
and would be something we would want/need to have feature parity if/when the
Router supports managing navigations with that instead of `History`.

With the deprecation of the configurable errorHandler in the Router, there is a missing
use-case to prevent the navigation promise from rejecting on an error. This rejection
results in unhandled promise rejections. This commit allows developers to instruct
the router to instead resolve the navigation promise with 'false', which matches
the behavior of other failed navigations.
Resolving the Promise would be the ideal default behavior. It is rare
that any code handles the navigation Promise at all and even more rare
that the Promise rejection is caught. Updating the default value for
this option should be considered for an upcoming major version.

There are cases where the application's default behavior is 'reload' and

The current way of computing a route's params and data recomputes
inherited data from the inheritance root every time. When the
inheritance strategy is "emptyOnly", this isn't necessarily the root of
the tree, but some point along the way (it stops once it reaches an
ancestor route with a component).
Instead, this commit updates parameter inheritance to only inherit data
directly from the parent route (again, instead of recomputing all
inherited data back to the inheritance root). The only requirement for
making this work is that the parent route data has already calculated
and updated its own inherited data. This was really already a
requirement -- parents need to be processed before children.
In addition, the update to the inheritance algorithm in this commit
requires more of an understanding that a resolver running higher up in
the tree has to propagate inherited data downwards. The previous
algorithm hid this knowledge because resolvers would recompute inherited
data from the root when run. However, routes that did not have resolvers
rerun or never had resolvers at all would not get the updated resolved data.

This adds `generate_api_docs` targets to all of the packages for which we publish api reference docs. One known issue here is that any type information that comes from another package (e.g. router depending on core) currently resolve to `any` because the other sources are not available in the program. This can be tackled in a follow-up commit.

This commit adds the ability to provide a function that will get called
immediately after the view transition is created. This will allow
developers to do things like add/remove classes from the DOM when the
transition animation is finished, skip the transition based on
application conditions, etc. Having access to the transition unlocks
just about every example outlined in https://developer.chrome.com/docs/web-platform/view-transitions.
Note that the timing of the `updateCallback` execution is in the spec as
being called asyncronously (https://drafts.csswg.org/css-view-transitions-1/#callbackdef-updatecallback).
This means the `onViewTransitionCreated` callback is guaranteed to
execute before the update callback which in turn means it is guaranteed
to execute before the view transition `ready`/animation. As a result, it
is safe/effictive to add classes to the document in the
`onViewTransitionCreated` function in order to control animations of
that transition and then remove those classes in the transition's `finished`
`Promise`. The animation also doesn't start until the `Promise` returned
by `updateCallback` resolves, so this would also guarantee that the
animation starts asynchronously.
