[mutter/gbsneto/graphene-matrix: 23/47] cogl/matrix: Remove custom boxed type

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

    cogl/matrix: Remove custom boxed type
    
    Given that CoglMatrix is simply a typedef to graphene_matrix_t, we can
    remove all the GType machinery and reuse Graphene's.
    
    Also remove the clutter-cogl helper, and cogl_matrix_to_graphene_matrix()
    which is now unused.
