In order to allow both signals and non-signals in two-way bindings, we have to pass the expression through `ɵunwrapWritableSignal`. The problem is that the language service uses a bundled compiler that is fairly new, but it may be compiling an older version of Angular that doesn't expose `ɵunwrapWritableSignal` (see https://github.com/angular/vscode-ng-language-service/issues/2001).
These changes add a `_angularCoreVersion` flag to the compiler which the language service can use to pass the parsed Angular version to the compiler which can then decide whether to emit the function.

Currently all triggers are set up to show the placeholder block on the server, except for `on immediate` which is basically a noop. These changes update `on immediate` to match the rest of the triggers.
Fixes#54385.

Getting the typing for `ɵunwrapWritableSignal` just right was tricky so these changes add some tests to ensure that we don't regress.
Also reworks the type tester a bit to make it easier to find where to add new test files.

This commit updates the implementation of the `customElements` patch and also
patches FACE callbacks (`formAssociatedCallback`, `formDisabledCallback`, `formResetCallback`
and `formStateRestoreCallback`). This now allows invoking those callbacks in the same zone
where the custom element has been defined.

Assure that the same readonly array corresponding to the children query results
is returned for cases where a query is marked as dirty but there were no actual
changes to the content of the results array (this can happen if a view is added
and removed thus marking queries as dirty but not influencing final results).

The newly introduced signal queries would error if no match exists, due to an

This commit addresses the crash by allowing there to be no matches.

Currently we have two fake copies of `@angular/core` in the compiler tests which can be out of sync and cause inconsistent tests. These changes reuse a single copy instead.

This updates some tests to use the public imports from `@angular/core` now that they are available,

In some situations, calling `markForCheck` can result in an infinite
loop in seemingly valid scenarios. When a transplanted view is inserted
before its declaration, it gets refreshed in the retry loop of
`detectChanges`. At this point, the `Dirty` flag has been cleared from
all parents. Calling `markForCheck` marks the insertion tree up to the
root `Dirty`. If the declaration is checked again as a result (i.e.
because it has default change detection) and is reachable because its
parent was marked `Dirty`, this can cause an infinite loop. The
declaration is refreshed again, so the insertion is marked for refresh
(again). We enter an infinite loop if the insertion tree always calls
`markForCheck` for some reason (i.e. `{{createReplayObservable() | async}}`).
While the case above does fall into an infinite loop, it also truly is a
problem in the application. While it's not an infinite synchronous loop,
the declaration and insertion are infinitely dirty and will be refreshed
on every change detection round.
Usually `markForCheck` does not have this problem because the `Dirty`
flag is not cleared until the very end of change detection. However, if
the view did not already have the `Dirty` flag set, it is never cleared
because we never entered view refresh. One solution to this problem
could be to clear the `Dirty` flag even after skipping view refresh but
traversing to children.

The `subscribe` methods on `ModelSignal` and `OutputEmitter` were marked as `@internal` which will break when the TCB needs to reference them. These changes make them `@deprecated` temporarily so we can address the properly later.

This helps with the Angular CLI currently swallowing fatal diagnostic
errors in ways that are extremely difficult to debug due to workers
executing Angular compiler logic.
The worker logic, via piscina, is currently not forwarding such Angular
errors because those don't extend `Error.`
https://github.com/piscinajs/piscina/blob/a7042ea27d129f3cad75c422f5aa92f0663854ee/src/worker.ts#L175
Even with access to these errors by manually forwarding errors, via
patching of the Angular CLI, there is no stack trace due to us not using
`Error` as base class for fatal diagnostic errors. This commit improves
this for future debugging and also better reporting of such errors to
our users- if we would accidentally leak one.

An identical addition to: 760b1f3d0b.
This commit expands the `try/catch`-es:
- to properly NOT throw and just convert the diagnostic.
- to be in place for all top-level instances. Notably, this logic cannot
reside in the template type checker directly as otherwise we would
risk multiple duplicate diagnostics.

Fixes that `ɵunwrapWritableSignal` inferring getter functions as not matching the interface of `WritableSignal` instead of preserving them.
PR Close#54252
In a previous commit the TCB was changed to cast the assignment to an input in order to widen its type to allow `WritableSignal`. This ended up breaking existing inputs whose setter has a wider type than its getter. These changes switch to unwrapping the value on the binding side.

Reworks the TCB for two-way bindings to make them simpler and to avoid regressions for two-way bindings to generic inputs. The new TCB looks as follows:

var _t2 = _t1.input;
(_t1 as typeof _t2 | WritableSignal<typeof _t2>) = expression;
```
