[gtk+] Drop ::proximity-in-event and ::proximity-out-event

[Matthias Clasen <matthiasc src gnome org>]

commit e93c2517e6d77a8fa0caae663540b6290deda000

    Drop ::proximity-in-event and ::proximity-out-event
    
    These are unused in GTK+, and are not very common.
    If you need to catch these events, the generic ::event
    signal still works.
