clutter-actor: Add an internal _clutter_actor_get_opacity_override

Browse Source 
This is needed if an effect wants to temporarily override the paint
opacity. It needs to be able to restore the old opacity override in
the post_paint handler otherwise it would replace the effect of the
opacity override from any outer effects.
