xwayland: Also hook screen's MoveWindow method

Browse Source 
Not only hook the ResizeWindow method of the screen (which really is
MoveAndResize) but also hook the MoveWindow method for checking if we
need to setup a viewport for resolution change emulation.

Our resolution change emulation check if the windows origin matches
the monitors origin and the windows origin can also be changed by just
a move without being resized.

Also checking on a move becomes esp. important when we move to checking
on changes to the top-level non-window-manager client (X11)Window instead
of on changes to the xwl_window later on in this patch series.
