[PATCH wayland] protocol: Add set_xwayland request for new shell surface type

X11 apps use global coordinates most of the time for window placement and the
current approach we have, where transient windows is placed parent relative,
is not sufficient. IOW we can't use the relation of parent <-> child
coordinates because we can't go out there and fix all the clients to place
subwindows relative.

Besides, it has to be a separate wl_shell_surface request specifically for
XWayland because we don't want stock Wayland applications using global
coordinates either.

At the moment only one method for XWayland windows was implemented, which is
the 'inactive' to not set focus when the window is configured. Later we will
want to add a few more methods for dealing with different types of windows.
