    keyboard: Unify OSK key commit handling in single-state signal
    
    Instead of having callers handle pressed+released, emit string
    commits on a distinct signal that is emitted all at once during
    release.
    
    This also unifies the behavior of keys that have an extended keys
    popup and not wrt press/release behavior and key repeat.
