[Feature]: Support outputFromObservable interop function for output

[bederuijter]

🚀 Feature Proposal

Angular 17.3 added outputFromObservable as interop function to create an output that emits the values of an observable stream. This simplifies passing values to an output when an observable stream emits.

public onChange$ = Subject<void>();
public isChanged = outputFromObservable(this.onChange$);

When the tests are run, the emitted values of isChanged are not captured by the tests.

    expect(jest.fn()).toHaveBeenCalled()

    Expected number of calls: >= 1
    Received number of calls:    0

A similar test in jasmine succeeds. Using the long-hand of manually subscribing to the stream and calling a output directly also works.

Motivation

It would be nice if outputFromObservable could be used, instead of needing to use the long-hand form, which involves manually needing to subscribing to the stream calling output instead
