[totem] build: Use template files for enums generation

[Iñigo Martínez <inigomartinez src gnome org>]

commit 54bce40ad443351e5c1b02a12b673cc18690e044

    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.
