xwm: don't do anything except mapping on MapRequest 

Instead, move the wlr_xwayland_surface_set_withdrawn() and
wlr_xwayland_surface_restack() calls to the MapNotify handler with an
override_redirect check, as they are done too early. This mirrors the logic in
the UnmapNotify handler and fixes a bug where wlr_xwayland_surface_restack()
would be called on an o-r window after the following sequence of requests:

- CreateWindow with override_redirect=True
- ChangeWindowAttributes with override_redirect=False
- MapWindow
