[gtk/global-coords] Drop gdk_device_get_position

[Matthias Clasen <matthiasc src gnome org>]

commit 1e49c4ef6a468d2343a8f44a1d7f8af44420a719

    Drop gdk_device_get_position
    
    Root coordinates are going away, so this
    api does not make sense anymore. Use
    gdk_surface_get_device_position instead.
    We still keep this as internal api for
    root-coordinate using backends.
