Chuck Jazdzewski be59c3a98c fix(common): weaken AsyncPipe transform signature (#22169)
The AsyncPipe type signature was changed to allow
deferred creation of promises and observalbes that
is supported by the implementation by allowing
`Promise<T>|null|undefined` and by allowing
`Observable<T>|null|undefined`.
