Enables users to add an array of FormControls to a FormArray using its existing .push() method,
instead of pushing each new FormControl one by one triggering events along the way.

This change also decorelate the `reset` type argument from `TValue` by adding a 3rd generic parameter to `AbstractControl`.
This improves the typings overall.
PR Close#55860
Adds the `markAllAsDirty` method to the `AbstractControl` class. This method will mark the control and all its
descendants as dirty.
I pretty much just duplicated the behaviour and tests of `markAllAsTouched`.

In the cases multiple updates with `emitEvent:false` were requests, `shouldHaveEmitted` wasn't passed correctly and and requests updates were trashed.
This commit fixes this.

This commit makes the host bindings of `NgControlStatus[Group]`
compatible with `OnPush` components. Note that this intentionally _does not_
expose any new APIs in the forms module. The goal is only to remove
unpreventable `ExpressionChangedAfterItHasBeenCheckedError` in the forms
code that developers do not have control over.

With this change, If an async validator that should have emitted was cancelled by a non-emitting validator, the status change will be reported on the `AbstractControl.events` observable.
This issue can happen when a `FormControl` is added to a `FormGroup` and a FormGroupDirective/FormControlDirective trigger a non-emitting validation (which cancels the initial validator execution).
Note: The behavior remains the same of the existing `statusChanges` observable as the change was too breaking to land in G3.

This commit deprecates the aliases for the control events to ease the changes in G3
A follow-up commit will remove those deprecated entries.

Since we aren't using clang anymore, we can remove the comments and the workarounds that were in place to prevent it from doing the wrong thing.

This commit introduces a new method to subscribe to on every `AbstractControl` subclass.
It allows to track value, pristine, touched and status changes on a given control.

The `Writable` type is usefull when we want overwrite readonly properties and we still want to maintain code navigation/reference. It should be use instead of `any` type assertions for example.

Fixes that the `AbstractControl` was mutating the validators arrays being passed into the constructor an helper methods like `setValidators`.

This commit exports existing utility functions to check for control instances:
isFormControl, isFormGroup, isFormRecord, isFormArray
Those are useful when implementing validators that use the specifics of one of those control types.
To narrow down the type to what it actually is, we can now use the util functions in validators:
```
export const myArrayValidator: ValidatorFn = (control) => {
if (!isFormArray(control)) { return null; }
// now you can use FormArray-specific members, e.g.:
if (control.controls.every(c => !!c.value) {
return { myerror: true }
} else { return null; }
}
```

The new `FormRecord` entity introduced in Angular v14 does not have its builder method.
This commit adds it, allowing to write:
```
const fb = new FormBuilder();
fb.record({ a: 'one' });
```
This works for both the `FormBuilder` and the `NonNullableFormBuilder`

DEPRECATED:
It is now deprecated to provide *both* `AbstractControlOption`s and an async validators argument to a FormControl. Previously, the async validators would just be silently dropped, resulting in a probably buggy forms. Now, the constructor call is deprecated, and Angular will print a warning in devmode.
DEPRECATED:
The `initialValueIsDefault` option has been deprecated and replaced with the otherwise-identical `nonNullable` option, for the sake of naming consistency.
In some places, the [@see][1] JSDoc tag was incorrectly used instead of
the [@link][2] inline tag, leading to warnings during doc generation and
the `@see` tags being ignored (and thus shown in the docs as is).
Replace the `@see` tags with the intended `@link` tags.
