[gnome-settings-daemon/wip/inigomartinez/meson: 3/6] build: Use template files for enums generation

[Iñigo Martínez <inigomartinez src gnome org>]

commit 3bbc5b0d0e5bf32717288b04777e0abc73614d48
Author: Iñigo Martínez <inigomartinez gmail com>
Date:   Thu Feb 1 22:25:54 2018 +0100

    build: Use template files for enums generation
    
    The data contents for the enum related files are stored in the
    build files.
    
    This patch moves this information to template files to be used
    along with glib-mkenums.
