[nautilus/wip/antoniof/new-pathbar: 6/6] pathbar: Refactor signals

[António Fernandes <antoniof src gnome org>]

commit 7285398c899ddc1af66b2ae6c26418ecf00a1b9a
Author: António Fernandes <antoniof gnome org>

    pathbar: Refactor signals
    
    NautilusPathBar::path-clicked is never emited.
    NautilusPathBar::location-changed uses a parameter type that's gone in
    GTK 4: GtkPlacesOpenFlags.
    
    Generate a GType for our own NautilusOpenFlags enum type to be used as a
    signal parameter, remove the unused signal and repurpose its signal
    handler to handle the second signal (which no longer has a signature
    compatible with the GtkPlacesSidebar one).
