[nautilus/gtk4-preparation-trunk: 18/36] files-view: Use popovers for context menus

[António Fernandes <antoniof src gnome org>]

commit 46b710c3b9ab19ab295ee439a4c410694b2fe7f0
Author: António Fernandes <antoniof gnome org>
Date:   Fri Dec 17 11:43:35 2021 +0000

    files-view: Use popovers for context menus
    
    GtkMenu is gone in GTK4. Prepare for the transition using GtkPopover.
    
    This is going to need design review after the GTK 4 switch, but it's
    good enough for the purpose of simplifying the switch.
    
    Closes https://gitlab.gnome.org/GNOME/nautilus/-/issues/738
