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.

Instead of iterating over all clients which are listening for events on the
root window and checking if the client we are dealing with is the one
listening for SubstructureRedirectMask | ResizeRedirectMask events and thus
is the window-manager, cache the client-id of the window-manager in
xwl_screen and use that when checking if a client is the window-manager.
Note that we cache and compare the client-id rather then the ClienPtr,
this saves reading the ClientPtr from the global clients array when doing
the comparison.

In between the two phases introduced by the previous change. This makes
sure all pending drawing to the new buffers is flushed before they're
committed to the Wayland server.
The first phase sets the new surface properties for all damaged
windows, then the second phase commits all surface updates.
This is preparatory for the next change, there should be no observable
change in behaviour (other than the order of Wayland protocol
requests).

Now that each source and header should be in order, we can safely cleaup
the last remaining bits from the main `xwayland.h` which is not needed
anymore and can be removed.
