[glib/gobject-speedups4] Add some tests around properties

[Matthias Clasen <matthiasc src gnome org>]

commit 2e8b51aaa8561e2edee029ee2fd444e3bdae136a
Author: Matthias Clasen <mclasen redhat com>
Date:   Tue Jun 7 12:02:58 2022 -0400

    Add some tests around properties
    
    Install the properties with a mixture of
    g_object_class_install_properties and
    g_object_class_install_properties, and verify
    that finding them still works, regardless of
    whether we use string literals or not.
