wayland: Use helper to translate to real parent window geometry

Browse Source 
Use a helper to translate a coordinate from non-real GdkWindow parent
to window geometry coordinate space of the real GdkWindow parent,
meaning the coordinate space of the GdkWindow of the parent used as a
xdg_popup parent where (0, 0) is inside of the shadow margin.
