[nautilus/wip/antoniof/gtk4-preparation-file-chooser-api: 3/3] general: Move to GFile-centric GtkFileChooser API

[António Fernandes <antoniof src gnome org>]

commit 7e98f3de309e8b8ae6cde1d80c86bc0e39c74be0
Author: António Fernandes <antoniof gnome org>
Date:   Wed Dec 22 23:48:26 2021 +0000

    general: Move to GFile-centric GtkFileChooser API
    
    This is going to make the switch to GTK 4 simpler, because URI and path-
    based API is gone there.
