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`.

This commit will fix the issue of the setting of NavigationExtras.replaceUrl being lost when
returning a urlTree from a CanActivateFn.
Fixes#53503
BREAKING CHANGE: When a a guard returns a `UrlTree` as a redirect, the
redirecting navigation will now use `replaceUrl` if the initial
navigation was also using the `replaceUrl` option. If this is not
desirable, the redirect can configure new `NavigationBehaviorOptions` by
returning a `RedirectCommand` with the desired options instead of `UrlTree`.

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 commit refactors the router module to enhance performance by substituting the startsWith method with direct access `[0]` when verifying the value of a single character. This optimization improves efficiency, as direct access retrieves the character's value stored at a specific index in the string, resulting in slightly faster execution.

This commit ensures components in the route config predictably always
get their providers from the hierarchy available to routes rather than
sometimes being dependent on where they are inserted.
fixes#53369
BREAKING CHANGE: Providers available to the routed components always
come from the injector heirarchy of the routes and never inherit from
the `RouterOutlet`. This means that providers available only to the
component that defines the `RouterOutlet` will no longer be available to
route components in any circumstances. This was already the case
whenever routes defined providers, either through lazy loading an
`NgModule` or through explicit `providers` on the route config.

This commit updates the logic around `Route.redirectTo` to enable using a
function to create the redirect. This function can return a string,
ands acts the same as previous string redirects, or a `UrlTree`, which
will act as an absolute redirect.
To be useful, the redirect function needs access to the params and data.
Today, developers can access these in their redirect strings, for
example `{path: ':id', redirectTo: '/user/:id'}`. Unfortunately,
developers only have access to params and data on the _current route_
today in the redirect strings. The params and data in the `RedirectFn`
give developers access to anything from the matched parent routes as
well. This is done as the same way as param and data aggregation later
on (https://github.com/angular/angular/blob/897f014785578d87bc655ea6ae9e113653960f50/packages/router/src/router_state.ts#L236-L278).
In order to accomplish this, we inherit params and data while
matching, after the `ActivatedRouteSnapshot` is created for the matched
route rather than waiting until the end.
The `RedirectFunction` does not return the full
`ActivatedRouteSnapshot` interface. Some things are not accurately known
at the route matching phase. For example, resolvers are not run until
later, so any resolved title would not be populated. The same goes for lazy
loaded components. The is also true for all the snapshots up to the
root, so properties that include parents (root, parent, pathFromRoot)
are also excluded. And naturally, the full route matching hasn't yet
happened so firstChild and children are not available either.
fixes#13373resolves#28661 (though not for the redirect string - you would return a
`UrlTree` from the function)
BREAKING CHANGE: This change allows `Route.redirectTo` to be a function
in addition to the previous string. Code which expects `redirectTo` to
only be a string on `Route` objects will need to be adjusted.

Returning `UrlTree` from a guard was a convenient new feature added to
the `Router`. However, it does not have feature-parity with the old
`router.navigate(...); return false;` pattern. The most common use-case
for this feature is to redirect to a new page _without_ updating the URL
from the initially attempted navigation. For example, rendering a 404
page when the user does not have access privelages to a route.

BREAKING CHANGE: Guards can now return `RedirectCommand` for redirects
in addition to `UrlTree`. Code which expects only `boolean` or `UrlTree`
values in `Route` types will need to be adjusted.

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.

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.

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 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.

The router currently restricts all further redirects after an absolute
redirect. Because there's no documented reason for _why_ this
restriction is in place, I'm now deeming this unnecessary. Developers
should not be restricted in this manner. Instead, configs that may
have caused infinite redirects in the past should be updated to not be
infinite. It is confusing to ignore configs with redirects after an
absolute redirect occurred because it creates different matching rules
depending on the whether an absolute redirect has happened or not.
For additional context on why I believe removing this restriction is
necessary, #13373 asks for allowing `redirectTo` to be a function. It
would make sense to allow this function to return a `UrlTree` like other
guards in the Router. When guards in the `Router` return `UrlTree`, they
cancel the current navigation and start a new one to re-do the route
matching. Since we're already in the router matching part, we don't need
to cancel the navigation. However, the restriction on absolute redirects
here then creates a weird situation where developers wouldn't see any
other redirects if they returned a `UrlTree` as an absolute redirect
from `redirectTo`.
resolves#39770
BREAKING CHANGE: Absolute redirects no longer prevent further redirects.
Route configurations may need to be adjusted to prevent infinite
redirects where additional redirects were previously ignored after an
absolute redirect occurred.
