[gtk+] Get rid of the focus_gtk vfunc

[Matthias Clasen <matthiasc src gnome org>]

commit 6d33c783d069ea8e3e5498c956997c477193aba5

    Get rid of the focus_gtk vfunc
    
    Only GtkWidgetAccessible and GtkWindowAccessible had implementations,
    and they could easily be converted to focus_event handlers.
