wayland: Emulate crossing for native window

Emitting a LeaveNotify event every time the pointer leaves an X11 window
may confuse focus follow mouse mode in window managers such as
mutter/gnome-shell.

Keep the previously found X window and compare against the new one, and
if they match then it means the pointer has left an Xwayland window for
a native Wayland surface, only in this case fake the crossing to the
root window.
