Prior to this change, binding to radio value was sensitive to the order in which `value` & `formField` where binding in the template.
The compiler change makes that order non-important.

(cherry picked from commit 65fa5b5439)
Add comprehensive test cases to validate behavior when multiple
pattern validators are applied to the same field.
These tests clarify that multiple patterns operate with AND logic,
where each pattern is validated independently and produces its own
error when it doesn't match.

This completes the rename started in #66136. `[field]` is too generic of
a selector for the forms system to own, and likely to cause naming
collisions with existing components. Therefore it is being renamed to
`[formField]`
(cherry picked from commit 5671f2cc07)
Remove the `customError` function and `CustomValidationError` type.
These were made obsolete by support for returning plain object literals
as custom errors.
This also catches few `field` properties that were missed in the
renaming to `fieldTree`.

Removes the abort event listener once the debounce timeout completes.
This avoids lingering listeners, prevents potential memory leaks, and ensures

The framework will now bind all field state properties to their
corresponding native properties (if any) on interop form controls (those
using `ControlValueAccessor`), excluding those handled explicitly by
`ControlValueAccessor` such as `disabled`.

The framework will now bind the field state properties to all matching

The framework will now bind the field state properties to all matching
directive inputs on custom form controls.
(cherry picked from commit 0c8f15d546)
Since the `Field` directive manages binding `FieldState` properties to
the underlying form control automatically, the type checker prohibits
explicit bindings to the same properties to avoid conflicts. This proved
problematic in cases where developers wanted to bind these properties to
the inputs of other directives on form controls. Now the framework will
bind the field state properties to all matching directive inputs on
native controls.

* Recognize directives with non signal-based models as valid custom controls
* Relax type checker to allow non signal-based models
The `FormValueControl` and `FormCheckboxControl` interfaces still
require a `model()`-input, however, a custom control need not implement
either interface to be bound by the `Field` directive.
All of the following examples can be used to define a custom control:
```ts
// Preferred: model()
class MyFormControl implements FormValueControl<string> {
readonly value: model.required<string>();
}
// Supported: input() + output()
class MyFormControl {
readonly value: input.required<string>();
readonly valueChange: output<string>();
}
// Supported: @Input() + @Output()
class MyFormControl {
@Input({required: true}) value!: string;
@Output() valueChange: new EventEmitter<string>();
}
```
The latter two may still choose to implement `FormUiControl` for other
properties, but again it is not required.
Fix#65478
(cherry picked from commit cb09fb8308)
Updates signal forms to pass the full `Field` directive to the class
configuration functions, rather than just the state. This allows
developers to take the element as well as the state into consideration
when deciding classes to apply.
Closes#65762
BREAKING CHANGE: The shape of `SignalFormsConfig.classes` has changed
Previously each function in the `classes` map took a `FieldState`. Now
it takes a `Field` directive.
For example if you previously had:
```
provideSignalFormsConfig({
classes: {
'my-valid': (state) => state.valid()
}
})
```
You would need to update to:
```
provideSignalFormsConfig({
classes: {
'my-valid': ({state}) => state().valid()
}
})
```

This PR makes a number of changes to the metadata API to address design
flaws in the previous API. Some of the changes include:
- Replaces the previous `MetadataKey` and `AggregateMetadataKey` with a
single unified `MetadataKey` that is used for all metadata.
- The new `MetadataKey` is only defined for fields that explicitly set
it in their schema logic
- All metadata now has reducer / aggregate behavior
- The new `MetadataKey` has an option to create a managed key which
wraps the result of its computed aggregate into some other structure
such as a `Resource` or `linkedSignal`
- There are now two APIs to create metadata keys
- `createMetadataKey` for pure computed metadata
- `createManagedMetadataKey` for metadata that manages its computation
internally

FormUiControl states that hidden, pending and dirty will be bind in custom controls, but this is currently not the case.
Fixes#65575
(cherry picked from commit 9fe9566581)
Previously, navigating a `FieldTree` in signal forms involved reactive reads
of the value of the parent field(s), both directly and via `.childrenMap()`.
This meant that on _any_ change to the value of a field, reactive
notifications would trigger updates of computeds, reruns of effects, etc.
So for example, this effect would run on every change to the form:
```ts
const f = form(signal({data: 'abc', unrelated: 0}));
effect(() => {
// accessing f.data incurs a dependency on f().value() which changes
// on every change in the whole form
console.log(f.data().value());
});
```
This is deeply counterintuitive and troublesome when attempting to write
effect logic, and also results in `computed`s unnecessarily updating.
This change introduces the concept of a "reader" computed, which memoizes
the access of a field at a given key via the reactive graph. With this, the
same `f.data` access above now depends on the `data` reader in `f` only,
which is effectively a constant computed. As a result, the effect only
reruns on changes to `data`'s value, as intended.

Support binding `[field]` to directives that implement

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.

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.

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.
(cherry picked from commit 98ce9a7b17)
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.
