quirks: add KDE quirk: surface must be damaged *after* being attached

KDE resets all surface damage when a buffer is attached. Add a quirk
that adds a full-buffer damage to the surface. This quirk is intended
to be called after attaching a buffer to a surface.

* On weston (8.0), synchronized subsurfaces aren't updated correctly.

* sporadic. Sometimes they update, most of the time they don't.
*
* Adding explicit parent surface commits right after the subsurface
* commit doesn't help (and would be useless anyway, since it would
* defeat the purpose of having the subsurface synchronized in the
* first place).
