[gnome-panel] don't use deprecated gtk_icon_size_register

[Alberts Muktupāvels <muktupavels src gnome org>]

commit 59951a69813159566644ef68b12e0a51ed01363a

    don't use deprecated gtk_icon_size_register
    
    Also 'gtk-icon-sizes' in themes are deprecated and ignored. That
    means that panel-menu and panel-menu-bar always is registered with
    default sizes - 24x24px and 16x16px. We can safely replace these by
    built-in stock icon sizes.
    
    This commit also restores limited option to change icon size. You
    can change icon size to one of built-in sizes - 16px, 24px, 32px
    and 48px.
