wayland: set window geometry to exclude the invisible CSD borders

Browse source 
But it *does* include the title bar. This simplifies the 'adjustment'
needed to be done to the configured window size.

It also fixes a number of issues:

* the compositor will now properly snap the window to screen
  edges (before, there was an empty space between the edge and the
  window - the CSD border).
* This also removes the need for the mutter 'commit' workaround. We
  must be doing something right now.
