This commit update the logic to enable `register` and `resolve` phases for local compilation. Those phases will be useful for local compilation in certain cases (will be used in followup PRs).

This commit splits the query implementation and instructions
into a separate files. This is a pattern frequently used by
other functional areas of the framework and is a preparation for
introducing queries-as-signals where we are going to see more
instructions delegating to the same core functionality.

Prior to this commit, `TestBed` would require tests call `flushEffects`
or `fixture.detectChanges` in order to execute effects. In general, we
want to discourage authoring tests like this because it makes the timing
of change detection and effects differ from what happens in the
application. Instead, developers should perform actions and `await` (or
`flush`/`tick` when using `fakeAsync`) some `Promise` so that Angular
can react to the changes in the same way that it does in the
application.
Note that this still _allows_ developers to flush effects synchronously
with `flushEffects` and `detectChanges` but also enables the <action>,
`await` pattern described above.

This commit moves the implementation of the change detection scheduler
used for testing to angular/core along with a (private export) provider function.
Note: Naming of the provider function is absolutely not final (and not
public API). I would prefer one that did not mention "zones"
but the easiest thing for now is to have a "Zone" and "Zoneless" naming
scheme.

We generate `advance` instructions before most update instructions and the majority of `advance` calls are advancing by one. We can save some bytes for the most common case by omitting the parameter for `advance(1)` altogether.

This addresses the offset issue caused when a switch case was empty with no spaces or children being affected by the markers that were added, but not accounted for in offset. The markers are not needed for empty content and can be safely removed in this case.

This commit ensures that change detection runs when an `LView` is
removed. Change detection is required because DOM nodes aren't actually
removed until the animation engine flushes and this doesn't happen until
the end of `detectChangesInternal` (`rendererFactory.end`).
PR Close#53812
The `afterRender` hooks currently run after `ApplicationRef.tick` but
also run after any call to `ChangeDetectorRef.detectChanges`. This is
problematic because code which uses `afterRender` cannot expect the
component it's registered from to be rendered when the callback
executes. If there is a call to `ChangeDetectorRef.detectChanges` before
the global change detection, that will cause the hooks to run earlier
than expected.
This behavior is somewhat of a blocker for the zoneless project. There
is plenty of application code that do things like `setTimeout(() =>
doSomethingThatExpectsComponentToBeRendered())`, `NgZone.onStable(() =>
...)` or `ApplicationRef.onStable...`. `ApplicationRef.onStable` is a
should likely work similarly, but all of these are really wanting an API
that is `afterRender` with the requirement that the hook runs after the
global render, not an individual CDRef instance.
This change updates the `afterRender` hooks to only run when
`ApplicationRef.tick` happens.

This flag is not actually read anywhere. It doesn't even have any effect
on the traversal algorithm because embedded views are always refreshed
in `Global` traversal mode during the refresh of their parent views.

The `ComponentFixture` code needlessly dances around the `ngZone` being
`null` when the `ComponentFixtureNoNgZone` option is set. Instead, it
can use the `NoopNgZone` to get the same effect without needing to have
checks all over the place for its presence.

In #52931, Kristiyan fixed a TemplateDefinitionBuilder bug in which derived alias variables in for loops (`$even`, `$first`, etc) were referring to the wrong level of nested `@for` block. (These variables are unique because they become inlined expressions, and are not "real" context variables.) He fixed this by appending level information to the generated alias name.
Template Pipeline actually suffered from the same bug. We fix it in a very similar way -- in particular, whenever these derived context variables are used, we make them depend on versions of `$index` and `$count` that have been suffixed with the xref of the enclosing repeater.
I have added a few more pipeline goldens, because we are not quite as clever as TDB about only generating the duplicate suffixed index and count variables when inside nested loops. This is fine, since in the long run, we want to refactor it more fundamentally.
I have also added a TODO to fix this more rigorously. In particular, it would be nice if we had proper support for shadowed variables, as well as unlimited levels of variables depending on one another.

Template pipeline previously mangled CSS property names like
`--camelCase` when used in host style bindings. Note: It still *does*
mangle these names in static style attrs, both in host bindings and on
elements. This is clearly wrong, but is consistent with what TDB does
today.

The diagnostic was catching the following case:
```ts
name = signal('Angular');
```
but not the following ones:
```ts
name = signal('Angular').asReadonly();
name = computed(() => 'Angular');
name!: Signal<string>
```
This was not catched in the tests because the type of `Signal` is different than the one actually used in core.
It turns out the real type forces the diagnostic to check both the `symbol.tsType.symbol` and the `symbol.tsType.aliasSymbol`.

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.

In order to provide a reasonable experience for Angular without Zones,
we need a mechanism to run change detection when we receive a change
notification. There are several existing APIs today that serve as the
change notification: `ChangeDetectorRef.markForCheck`, signal updates,
event listeners (since they mark the view dirty), and attaching a view to
either the `ApplicationRef` or `ChangeDetectorRef`. These operations
are now paired with a notification to the change detection scheduler.
The concrete implementation for this scheduler is still being designed.
However, this gives us a starting point to partner with teams to
experiment with what that might look like.

The way we were handling ICU placeholders was not compatible with using
interpolations on attributes of elements inside the ICU. This change
refactors the handling of ICU placeholders and unifies the way
expression and tag placeholders work inside ICUs.
The new approach modifies the ingest logic to add the placeholder on to
the TextOp rather than the TextInterpolationOp. This is because, in
ICUs, we may need multiple i18n expressions created from the
interpolation expressions to roll up into the same placeholder. ICUs
essentially do the interpolation at compile time, combining the static
strings with special placeholder strings that represent the expression
values.

When an application does not use zones, it does not need a default value
for the zone stableness token. This will allow zoneless applications to
tree-shake a lot of rxjs operators out of `ApplicationRef`.
Note that at the moment, `provideZoneChangeDetection` is included in all
applications as well as the `TestBed` environment. It is not currently
possible to remove the zone stable code as a result. This will be
possible only when we make zones an opt-in rather than opt-out.

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.

It's possible for the user to create a host attrbiute binding with a
name that makes it _look_ like a class binding `{['class.foo']: ''}`, we
were previously treating these as actual class property bindings. This
change fixes the logic so that only true property bindings cam be
converted to class property bindings.
Note: A user who added an attribute like the above almost certainly
intended to create an actual class property binding. It would be nice if
we could add a diagnostic to warn them about this.
