gtkmodelmenu: move to new action regime

Browse Source 
Drop the explicit passing of GActionGroup into the GtkMenu(Bar)
constructors and operate from the action context instead.

With GtkMenuItem implementing GtkActionable, this turns out to be pretty
easy (and most of the code can be removed from GtkModelMenuItem,
including the GActionObserver implementation).
