Martin Gräßlin ce8c4240f7 [kwin_wayland] Create a dedicated Surface class
A Surface class is split out which holds a wl_surface and supports
attaching a buffer, setting the damage and emitting a signal when the
frame callback got called.

It doesn't come with a unit test yet as it first needs the ShmPool
and Buffer properly split out to easily set it up.
