wayland: Add get_monitor_at_window to Wayland backend

Given that Wayland has no global coordinate, the only way for gdk to
retrieve the monitor a window last entered is to retrieve it from the
GdkWaylandWindow itself.

Implement the backend specific get_monitor_at_window() to return the
monitor that was last entered by the window.
