cogl/matrix: Make CoglMatrix a typedef to graphene_matrix_t
After the previous commit, the only field in the CoglMatrix structure is a graphene_matrix_t. That means that CoglMatrix is effectively a graphene matrix now, and the CoglMatrix struct isn't that much useful anymore. Remove the CoglMatrix structure and make the CoglMatrix type a typedef to graphene_matrix_t. https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1439
