[nautilus/gtk4-preparation-trunk: 7/60] pathbar: Refactor signals

[António Fernandes <antoniof src gnome org>]

commit 997d5b9bb9de8a0e12604db8aaf944307fae16a3
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).
