Feature Request: Only emit values if status is valid

[lothern]

Description

Love this project! I find it superior to the typed forms in Angular 14 and really appreciate your authoring/maintaining of this library. Thank you!

I use RxJS heavily in my projects and I very often observe the value of your typed AbstractControl via the value$ property, and that works great. I have recently encountered a situation where I would like to only receive emitted values if the status of the AbstractControl is valid.

Proposed solution

Add new property validValue$ which emits a value only if the control is valid.

Alternatives considered

Considered implementing outside the library, but that burdens users with the unnecessary details of implementing it themselves.
