[PATCH gtk-3-22] wayland: apply input shape and opaque region

For subsurfaces, the new state which includes the input shape and opaque
region is not applied by the compositor if the subsurface is in
effective synchronous mode.

So we need to apply the input shape and opaque region once the
subsurface is desynchronized and its parent surface is in effective
desynchronized mode, which is when the parent surface is committed,
otherwise these may never be applied if the widget is not using
being_paint()/end_paint() (like clutter).
