[gnome-builder] greeter: propagate selection mode

[Christian Hergert <chergert src gnome org>]

commit c1f6f81f1dbb5269ceea10c452cc192537719e81

    greeter: propagate selection mode
    
    This notifies the sections to enter selection mode, or exit
    selection mode. We still need the ability to notify of active
    selections and to perform an action, but that will happen in a
    future commit.
