wayland: Wire in surface mapped state

Browse source 
If a sub-surface should be considered unmapped, make the corresponding
item invisible.

Note that this must apply only to sub-surfaces. Whether the main surface
should be visible is up to kwin. It may want to play an animation when
the toplevel surface is unmapped, etc.
