[mutter] clutter/image: Port to G_DECLARE_DERIVABLE_TYPE

[Marge Bot <marge-bot src gnome org>]

commit a2c999b6b1d9638cc652f131862deee632dabad6
Author: Georges Basile Stavracas Neto <georges stavracas gmail com>
Date:   Thu Mar 31 12:56:53 2022 -0300

    clutter/image: Port to G_DECLARE_DERIVABLE_TYPE
    
    Cleanup all the boilerplate, and port the function to use the auto
    generated private helper. Remove the manual autocleanup declaration
    since this is now done in the clutter-image.h header.
