wayland/surface: Schedule updates in the context of the surface actor

Browse Source 
This makes all stage updates that result from applying the pending
state of a Wayland surface emit an "update-scheduled" signal in the
context of the relevant surface actor.

A common case where an "update-scheduled" signal is needed is
when applying "empty" client commits. In this case a
"repaint-scheduled" signal would not be emitted since the commit
doesn't trigger a repaint. However, it is still important to add
handling for such updates with variable refresh rate when the
releavnt actor is also driving the refresh rate.
