Prior to this change, the `validators` and `asyncValidators` fields of a few Forms directives
were typed as `any[]`. This commit updates the types and makes them consistent for all directives
in the Forms package.
BREAKING CHANGE:
Directives in the `@angular/forms` package used to have `any[]` as a type of `validators` and
`asyncValidators` arguments in constructors. Now these arguments are properly typed, so if your
code relies on directive constructor types it may require some updates to improve type safety.

It's perfectly valid for an abstract control not to have a defined parent; yet previously the
types were asserting that AbstractControl#parent is not a null value. This changes correctly
reflects the run-time behavior through the types.
BREAKING CHANGE: Type of AbstractFormControl.parent now includes null
`null` is now included in the types of .parent. If you don't already have a check for this case,
the TypeScript compiler might compain. A v11 migration exists which adds the not-null assertion
operator where necessary.
In an unlikely case your code was testing the parnet against undefined with sitrct equality,
you'll need to change this to `=== null` instead, since the parent is not explicily initialized
with `null` instead of being left `undefined`.

NG_VALUE_ACCESSOR is a multi injection token, users can and
should expect more than one ControlValueAccessor to be
available (and this is how it is used in @angular/forms).
This is now reflected in the definition of the injection token
by typing it as an array of ControlValueAccessor. The motivating
reason is that using the programmatic Injector api will now
type Injector#get correspondingly.
fixes#29351
BREAKING CHANGES
NG_VALUE_ACCESSOR is now typed as a readonly array rather than
a mutable scalar. It is used as a multi injection token and as
such it should always be expected that more than one accessor
may be returned.

This commit refactors the way we store validators in AbstractControl-based classes:
in addition to the combined validators function that we have, we also store the original list of validators.
This is needed to have an ability to clean them up later at destroy time (currently it's problematic since
they are combined in a single function).
The change preserves backwards compatibility by making sure public APIs stay the same.
The only public API update is the change to the `AbstractControl` class constructor to extend the set
of possible types that it can accept and process (which should not be breaking).

Moves the public api .d.ts files from tools/public_api_guard to
goldens/public-api.
Additionally, provides a README in the goldens directory and a script
assist in testing the current state of the repo against the goldens as
well as a command for accepting all changes to the goldens in a single
command.
