clutter/actor: Remove get_default_paint_volume() API

These days it's possible to chain up into the default get_paint_volume()
implementation again, which renders
clutter_actor_get_default_paint_volume() unnecessary. So remove that
function and move clutter_actor_update_default_paint_volume() back into
real_get_paint_volume() where it belongs.

- * clutter_actor_get_default_paint_volume:

- * This function should only be used by #ClutterActor subclasses that
