[gnome-software] gs-content-rating: Expose list of all OARS categories

[Richard Hughes <rhughes src gnome org>]

commit 46b988ede900d648ba65f478742f49d81f549997

    gs-content-rating: Expose list of all OARS categories
    
    This is equivalent to `as_content_rating_get_all_rating_ids()`, but we
    can use it without bumping our appstream-glib dependency. It could
    eventually be dropped once we depend on appstream-glib ≥ 0.7.15.
