Following https://github.com/angular/angular/pull/64509 we started
choking on unbalanced closing parentheses in declaration blocks,
specifically in quoted background-image urls. This was reported in
https://github.com/angular/angular/issues/65137.
This occured because we previously (and now again) traverse the entire
declaration block when selecting for :host-context() selectors to shim.
This is an oddity of how we parse styles today, and is likely something
we'd want to remove if we parsed selectors properly.
This change adds a new flag to _splitOnTopLevelCommas which allows it to
continue past unbalanced closing parentheses in the declaration block,
returning _convertColonHostContext to its previous behavior while
keeping support for the extra nesting in :host-context().

We didn't get much report on the feature itself so we feel confident about promoting it to stable. In parallel we'll also land #62959 but one is not blocking the other.

It can be useful for a developer to set `NaN` as the value for a number
input, as a way to say "clear the input". However, directly setting this
value to the `.valueAsNumber` causes a console warning. This PR fixes
the console warning by just doing `.value = ''` when we would otherwise
to `.valueAsNumber = NaN`

An early piece of feedback received regarding custom controls hosted on
native inputs was that they required a lot of boilerplate to bind
`FieldState` properties. Each property required an input to accept the
property, and a host binding to forward it to the native control.

Although the prior commit has made more profiler events guaranteed symmetric
through the use of finally-blocks, there continue to be some situations
that could potentially result in asymmetric events, e.g. application
bootstrap doesn't guarantee symmetric events. This commit makes the profiler
lenient to these situations by unrolling the stack past the asymmetric event
data, eventually reaching the expected start event.
(cherry picked from commit da9911f2b4)
Profiler events are expected to be symmetric, yet in the case of errors this symmetry may break
if events aren't always kept in sync with their corresponding start event. This commit moves
various end events to be run from a finally-block, allowing them to notify the profiler even
when an error has occurred.

* Apply any debounce rules to updates from interop controls (if configured).
* Add tests to ensure debouncing works for all control types (native, custom,
and interop).

If we're calling `min` on a path that's guaranteed to be `number` we
don't want to make the users validator function handle the `null` or
`string` cases.
This uncovered an issue in the `SchemaTreePath` type which needed to be
fixed by preventing the model type from being distributed over.

Relaxes the constraints on which paths can be used with the `min` &
`max` validation rules, since people may want to validate a

The `type_check_block.ts` file was getting quite large and difficult to navigate. These changes split up the different pieces of functionality into separate files.

Test that a component with a bound `[field]` input is not treated as a

In cases the `ngDevMode` flag hasn't been set, still enable the formatter. What matters is if `ngDevMode` is `false ` we tree shake that away.

Add an `AbortSignal` parameter to `Debouncer`. Implementations may
choose to accept this parameter to be informed when a debounced
operation is aborted. This may be useful for canceling pending timers or
avoiding unnecessary work.

Reworks the way we approach type checking of signal forms to be closer to the behavior at runtime. There are a couple of scenarios that we handle:
1. For native controls, we now produce simplified type checking code that looks as follows:
```
var t1 = null! as number | string; // Type depends on the input `type`.
t1 = someField().value();
```
2. For custom controls we generate bindings to the individual inputs, rather than checking conformance against `FormValueControl`/`FormCheckboxControl`. This is closer to the behavior at runtime and it allows us to handle generic directives properly.

:nth-child() (and its siblings) support complex expressions, e.g.
`:nth-child(2n of :is(.foo, .bar))`. Previously we'd choke because of
the `:is()`. Now, we reuse the `_parenSuffix` subexpression to match
nested parentheses the same way we do for :host() and :host-context().
Note that we only support 3 levels of nesting, so a selector like
`:nth-child(n of :is(:has(:not(.foo))))` will still break.
I'll say yet again that we really should add a proper parser so we stop
getting bug reports like this :)

The `debounce()` rule allows developers to control when changes to a
form control are synchronized to the form model.
This feature necessitated some changes to `FieldState`:
* `controlValue` is a new signal property that represents the current
value of a form field as it appears in its corresponding control.
* `value` conceptually remains unchanged; however, its value may lag
behind that of `controlValue` if a `debounce()` rule is applied.
The `debounce()` rule essentially manages when changes to `controlValue` are
synchronized to `value`. The intent is that an expensive or slow
validation rule can react to the debounced `value`, rather than a more
frequently changing `controlValue`.
Directly updating `value` immediately updates `controlValue`, and cancels any
pending debounced updates.
When multiple `debounce()` rules are applied to the same field, the last
currently active rule is used to debounce an update. These rules are
applied to child fields as well, unless they override them with their
own rule.

The flag `skipFormatting` got renamed to `ngSkipFormatting` during review of https://github.com/angular/angular/pull/64000, but a couple usages got missed, causing some unfortunate UI recursion.

The `fullInheritane` flag from the metadata and the `CopyDefinitionFeature` that it controls appear to no longer be used since `fullInheritance` is always false. The feature appears to have been there to support ngcc which was removed some time ago.

Prior to this commit, attempting to resolve a `ChangeDetectorRef` after views or app have been destroyed would result in an error. In this commit, we clean up listeners once the view is destroyed, before the placeholder loads or fails to load.

Wraps InjectionToken names with `typeof ngDevMode !== 'undefined' && ngDevMode`
checks to enable tree-shaking of descriptive token names in production builds.
This ensures debug-only strings are removed from production bundles, reducing size.
Also removes unused imports found during refactor.

Annotate the `new Version(...)` call with `/* @__PURE__ */` to signal to optimizers that the constructor is side-effect free.
Without this hint, bundlers such as Terser or ESBuild may conservatively retain the `VERSION` instantiation even when unused. With the annotation, the constant can be tree-shaken away in production builds if not referenced, reducing bundle size.
