Provide vsync id for PiP animation

The vsync-id is attached to every SurfaceControl.Transaction within
PipAnimationController and therefore it's available to onAnimationStart,
onAnimationEnd as well as onAnimationUpdate.

What's next: may need to provide vsync id for PiP animation running in
Launcher process as well.
