wayland: Drive frame callbacks from stage updates

Browse source 
Don't tie frame callbacks to actor painting, as it may end up in
situations where we miss sending frame callbacks when we should have. An
example of this is when a surface is partially off screen, and then
reports damage that is fully off screen. When this happen, we are likely
not to repaint anything, thus we won't send any frame callbacks even
though it's "suitable" for rendering again, as the surface is not on a
separate workspace or fully obscured.
