compositor: damage the whole buffer on viewport src change 

wp_viewporter protocol doesn't seem to say anything about damage, but
Firefox assumes that wp_viewport::set_source alone is enough to damage
the whole surface, and that assumption kinda makes sense, so let's do
that.

(cherry picked from commit da2491d4163e1d8e627d00c8ae594c7f8003472e)
