Allow a FormControl to be reset to its initial value. Provide this feature via a new option in a FormControlOptions interface, based on AbstractControlOptions.
Also, expose the default value as part of the public API. This is part of a feature that has been requested elsewhere (e.g. in #19747).
This was originally proposed as part of typed forms. As discussed in the GDE session (and after with akushnir/alxhub), it is likely better to just reuse the initial value rather than accepting an additional default.
It is desirable to land this separately in order to reduce the scope of the typed forms PR, and make it a types-only change.
Pertains to issue #13721.

This reverts commit cdf50ff931.
Reverting as this needs a little more work on the documentation side, plus
the `export declare interface` syntax in `model.ts` might have unintended
side effects in g3.
This implementation change was originally proposed as part of Typed Forms, and will have major consequences for that project as described in the design doc. Submitting it separately will greatly simplify the risk of landing Typed Forms. This change should have no visible impact on normal users of FormControl.
See the Typed Forms design doc here: https://docs.google.com/document/d/1cWuBE-oo5WLtwkLFxbNTiaVQGNk8ipgbekZcKBeyxxo.

This commit makes the `FormControlStatus` symbol available as a public API. The symbol itself
was intended to become a part of the public API, but due to the missing re-export, the symbol
remains private.
Fixes#44176.

This commit updates the code of the min/max and minlength/maxlength validator directives to inherit `ngOnChanges` hooks from the base class (the `AbstractValidatorDirective` one), rather than implementing the hooks on the child classes. This was needed to avoid issues with hooks inheritance in ViewEngine, but since it's deprecated, the code can be cleaned up.

Updates all API goldens to match with the new NPM package output
which now contains partial declaration static members. These
can serve as additional checks guarding against changes to
the public API (e.g. if a selector of a directive changes accidentally)

This commit updates the logic of the `min` and `max` validators to allow
disabling them dynamically in case `null` is provided as a value. For example: `<input
type="number" [min]="minValue">`, when `minValue` might be set to `null` in a
component class. This should allow `min` and `max` validators to be used for dynamic forms.
Note: similar support was added to the `minLength` and `maxLength`
validators earlier (see #42565).

Specifically: narrow the type used for form statuses from string to a union of possible statuses. Change the API methods from any to use the new type.
This is a breaking change. However, as discussed in the PR, breakage seems minimal, and google3 has been prepped to land this.
Background: we uncovered these any typings in the course of design work for typed forms. They could be fixed in a non-breaking manner by piggybacking them on top of the new typed forms generics, but it would be much cleaner to fix them separately if possible.
BREAKING CHANGE:
A new type called `FormControlStatus` has been introduced, which is a union of all possible status strings for form controls. `AbstractControl.status` has been narrowed from `string` to `FormControlStatus`, and `statusChanges` has been narrowed from `Observable<any>` to `Observable<FormControlStatus>`. Most applications should consume the new types seamlessly. Any breakage caused by this change is likely due to one of the following two problems: (1) the app is comparing `AbstractControl.status` against a string which is not a valid status; or, (2) the app is using `statusChanges` events as if they were something other than strings.

Several new functionalities are possible with this change: the most requested is that callers can now check whether a control has a required validator. Other uses include incrementally changing the validators set without doing an expensive operation to reset all validators.
Closes#13461.
