clutter/actor: Clarify things about the last painted paint volume a bit

Browse Source 
Rename the `last_paint_volume` to `visible_paint_volume`: That avoids
confusion with the `had_effects_on_last_paint_volume_update` flag and
also makes it clear that this paint volume is the currently visible one.
