Cherry-pick: aw: Skip hardware onDraw when visible rect is empty
Clean cherry-pick of crrev.com/693c6a04c69d69a1240e4b83e2ec7fea459acda4
Framework does not clamp onDraw to only the visible area. However must
still request functor in this case to support rt-side animation, and to
obtain the correct draw matrix. This means HardwareRenderer must be able
to handle not having a parent frame available.
