Introduce a new configuration option `unmatchedInputBehavior` to the `componentInputBinding` feature. This option allows users to configure the behavior when a component input is not matched by any key in the router data.
The available values are:
- 'alwaysUndefined': (Default) Always binds undefined to unmatched inputs.
- 'undefinedIfStale': Binds undefined only if the input was previously available in the router data for the active route in the outlet.
This feature addresses concerns raised in #63835 and #52946 regarding the retention of default values for inputs that were never targeted by the router, while still ensuring that stale data is cleared when a parameter is removed.
Add `ComponentInputBindingOptions` which is used with `withComponentInputBinding` and `bindToComponentInputs`
Can set which sources to bind as follows:
* queryParams
* params
* data
feat(router): Add `options` optional parameter for `withComponentInputBinding`
Add missing ternary operator for queryParams
Updates the selector for `RouterOutlet` to allow for it to be set on an `ng-container`. This allows it to not render the host node which can affect the layout.
Fixes#64553.

This is effectively a revert of https://github.com/angular/angular/commit/72e6a948bb8ec58f14b87d297d5f81baf2e1942d.
Debugging the recognize stage is considerably easier with async/await
stacks compared to rxjs. This also improves maintainability and is a
better 1:1 with server-side logic that has been implemented to match
and can be more easily kept in sync.
This also ensures that the recognize step is always async, whereas it
can sometimes be synchronous with rxjs.
BREAKING CHANGE: Router navigations may take several additional
microtasks to complete. Tests have been found to often be highly
dependent on the exact timing of navigation completions with respect to
the microtask queue. The most common fix for tests is to ensure all
navigations have been completed before making assertions. On rare
occasions, this can also affect production applications. This can be
caused by multiple subscriptions to router state throughout the application,
both of which trigger navigations that happened to not conflict with the
previous timing.

This updates async router tests to use the jasmine autoTick feature. Observed test timings
for the chromium tests went down from ~7.5s to ~3.5-4s. For node, these decreased from ~5.5s to ~3s.
In addition to the speed improvement, this feature:
* Removes the need to be careful about timeout ordering when there are several timeouts in tests.
* Removes the need to ensure test timeouts are kept sufficiently small
* Reduces overall flakiness

There is nothing in the Router that requires ZoneJS and we do not need
`fakeAsync` as a mock clock. We can instead use any mock clock implementation
to speed up test execution.
This removes ZoneJS completely from the bundle of the Router tests.
ZoneJS causes the stacks to be unreadable when combined with the massive
rxjs stack in the router transition.

BREAKING CHANGE:
This commit deprecates `ng-reflect-*` attributes and updates the runtime to stop producing them by default. Please refactor application and test code to avoid relying on `ng-reflect-*` attributes.
To enable a more seamless upgrade to v20, we've added the `provideNgReflectAttributes()` function (can be imported from the `@angular/core` package), which enables the mode in which Angular would be producing those attribites (in dev mode only). You can add the `provideNgReflectAttributes()` function to the list of providers within the bootstrap call.

This commit moves zoneless from experimental to developer preview.
* Update tag on provider API
* Remove "experimental" from provider name
* Move documentation from "experimental features" to "Best practives ->
Performance" (at least temporarily until there is a better place)
BREAKING CHANGE: `provideExperimentalZonelessChangeDetection` is
renamed to `provideZonelessChangeDetection` as it is now "Developer
Preview" rather than "Experimental".

This commit adds an input to `RouterOutlet` that allows developers to
pass data from a parent component to the outlet components.
Setting the `routerOutletData` input on `RouterOutlet` makes the value
available to the child component injectors via the `ROUTER_OUTLET_DATA`
token. This token uses a `Signal` type to allow updating the input value
and propogating it to the token rather than needing to make the value
static.

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.

`RouterOutlet` components can initialize _during_ change detection (for
example, if they exist in an embedded view). When this happens, data
from the router should be bound immediately to the routed components
rather than not being available until the next round of change
detection. This is mostly just a problem for testing because change
detection is triggered manually. It would be surprising to have to
detect changes _twice_ on the fixture in order to get data bound to the
routed component.

`RouterTestingModule` is not needed as of v16. Instead, TestBed
automatically provides `MockPlatformLocation` in order to help test
navigations in the application. The location mocks in the
RouterTestingModule aren't necessary anymore.
There doesn't appear to be any real documentation around
`RouterTestingModule` other than the API docs.

The easiest way to access route data is now to use direct bindings to
component inputs rather than going through `ActivatedRoute`.
The tour of heroes guide still uses `ActivatedRoute` for now. I was
hesitant to remove all of the content in one swoop and the tour of
heroes is quite a bit more involved.

Adds ability for `RouterOutlet` to bind `Router` information to the routed
component's inputs. This commit also exposes some helpers for
implementers of custom outlets to do their own input binding if desired.

This commit updates the 'name' of `RouterOutlet` to be an `Input` rather
than an attribute. Note that this change does not affect `[attr.name]=`
because those already would not have worked. The static name was only
read in the constructor and if it wasn't available, it would use
'PRIMARY' instead.
fixes#12522
BREAKING CHANGE: Previously, the `RouterOutlet` would immediately
instantiate the component being activated during navigation. Now the
component is not instantiated until the change detection runs. This
could affect tests which do not trigger change detection after a router
navigation. In rarer cases, this can affect production code that relies
on the exact timing of component availability.
