[glibmm/glibmm-2-62] Glib::Checksum, DateTime, TimeZone: Add Glib::Value<> specializations

[Kjell Ahlstedt <kjellahl src gnome org>]

commit 6dd340c95c18ac2c6164d5759ab04bc562b6021b
Author: Kjell Ahlstedt <kjellahlstedt gmail com>
Date:   Tue Sep 17 15:09:00 2019 +0200

    Glib::Checksum, DateTime, TimeZone: Add Glib::Value<> specializations
    
    With Glib::Value<> specializations these classes can be used in
    Glib::Value<> and _WRAP_PROPERTY.
    See https://mail.gnome.org/archives/gtkmm-list/2019-April/msg00012.html
