Within the language service, the Angular compiler instance can provide
access to the current TypeScript program via `getCurrentProgram`. By
using the compiler, the need to pass around the program driver is no longer
required and can also be removed as an instance field of the Angular language
service class. This change also provides a higher assurance that the correct
program is being used throughout each language service request.

Prior to this change, `NgZone` was provided by default in TestBed in a
location that would override anything configured in
`TestBed.initTestEnvironment`. This change moves the default `NgZone`
provider to the `RootScopeModule` and these providers can be overridden
by the ones in `additionalModuleTypes`, which are assigned from the
first argument of `initTestEnvironment`. This makes it possible to
configure Zone globally for all tests as opposed to needing to repeat it
in `configureTestingModule` of each suite.

Now that #55092 has merged, we now consistently get the `setTimeout` and
`rAF` implementations that are not patched by zone. There's no longer a
need to run them in the root zone.

PR #55099 updated zoneless behavior to treat all views attached to
`ApplicationRef` as `OnPush`. Put another way, Zoneless change detection
will only refresh view trees that notified Angular of a change. This
generally works as expected but there was one situation where it did
not.
Some views are logically linked to their declaration locations and
should refresh when the declaration refreshes. These views are called
"transplanted views" and work correctly when inserted into another view
container. This change updates the logic to also work when they are
attached directly to `ApplicationRef`.

Previously the input flags were being generated as a reference to an enum member for better readability and under the assumption that minifiers would inline the values. That doesn't appear to be the case so these changes switch to using the literal values instead.

The fix from PR #55079 introduced a configuration of the injector chain, which wasn't properly handled by the injector debug utils, thus resulting in JS exceptions in DevTools. This commit updates injector debug utils logic that calculates injector resolution path to also handle `ChainedInjector`s.

In #52110 we had to use `if` statements to represent `switch` blocks, because TypeScript had a bug when narrowing the type of parenthesized `switch` statements. Now that it has been fixed by TypeScript and we don't support any version that has the broken behavior, we can go back to generating `switch` statements in the TCB which are simpler and better represent the user's code.

Grabbing and saving the references to global `setTimeout` and `rAF`
implementations at a certain point in time can be problematic, espcially
in tests. Tests might call something like `jasmine.clock().install();`
and `jasmine.clock().uninstall();`. If the install happens before we
grab the implementation and then the uninstall happens after, our
scheduling function will be broken because it would have saved a reference to
the jasmine `setTimeout` implementation, which would have since been
cleaned up and will throw an error when attempting to access `delayedFunctionScheduler`.
There are other scenarios that may apply, not even just for tests, when
patches are applied and removed to the globals.

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.

Returning a `RedirectCommand` from a resolver can be interpreted as
distinctly different from regular resolved data. When a resolver returns
`RedirectCommand` we can interperet this as an intention to redirect in
the same way as other guards.

The control flow migration was using a couple of Greek letters as placeholders. This ended up conflicting with templates authored in Greek.
These changes use a more obscure placeholder to make conflicts less likely. It also moves the placeholder generation to a centralized function so it's easier to make changes if we decide to update the pattern again.
Fixes#55085.

This change treats all views attached to `ApplicationRef` as `OnPush`,
meaning that they have to be explicitly marked for check in order to be
refreshed when a tick happens. This prevents "accidentally" refreshing
views which have `Default` change detection as a side effect of running
change detection from an unrelated notification.
In addition, this change helps us achieve one of the big goals of the
project: that we can provide a testing experience which gives developers
more confidence that a component is zoneless-compatible. Because
`ComponentFixture` change detection is run through `ApplicationRef`
instead of `ChangeDetectorRef` when zoneless is enabled, this ensures
that the component under test has correctly been marked for check in
order to be updated. Without this, calling
`ComponentFixture.detectChanges` would allow a test to _force_ change
detection on a view when Angular would have otherwise not known that it
needed to be updated. Calling `ComponentFixture.detectChanges` on a component
which is not marked for check will now omit refreshing component view.

Rework the i18n cleanup behavior to more closely match that of containers. Specifically, we assume that nodes are going to be claimed unless they are part of a branching ICU block.
During hydration, we then track which ICU case was active at serialization time, and which was active during hydration. Any remaining cases that weren't used during hydration are then cleaned up.
PR Close#54823
Add support for hydrating i18n blocks. This is accomplished by serializing information about selected ICU cases for a block during server-side rendering.
During hydration, this data is read and is used to traverse both an AST of the translated message and the DOM, in parallel, to map each LView with an RNode.
Finally, this mapping is used while nodes are being created (either via i18n or their respective instructions) to locate existing nodes.

This commit updates the internal resolve value of the navigation promise
to use `false` instead of `null` when a navigation is skipped. The
navigation promise type requires `boolean` so the correct resolution to
match the truthy/falsiness of the currently resolved value, `null`, is
`false` instead.

This commit moves the call to the error handler to the location where
the error event emits instead of having it indirectly work through the
events subscription. This change would also allow the handler to return
a value which can be handled by the navigation transition.

This commit fixes the types on the error handler resolve and reject
functions and also ensures that the resolve value matches the API type
(`boolean`, not "any random value returned from `errorHandler`"). This
could be considered a breaking change but I would argue instead that
relying on the return value of the error handler is API misuse because
the promise returned by the router navigation _does not_ include `any`
in its type.
PR Close#55068
This commit fixes the internal types for the resolve and reject
