window-actor/wayland: Remove custom get_paint_volume() vfunc

Browse Source 
It doesn't take all children - subsurfaces in this case - into
account, thus creating glitches if subsurfaces extend outside
of the toplevel surface.

Further more it doesn't seem to serve any special purpose - it was
added in f7315c9a36, a pretty big commit, and no discussion was
started about the code in question. So it was likely just overlooked
in the review process.
