translate: implement translation of 10_10_10_2 types
This is for GL_ARB_vertex_type_2_10_10_10_rev.
I just took the code from u_format_table.c. It's based on pack_rgba_float.
I had no other choice. The u_format hooks are not exactly compatible
with translate. The cleanup of it is left for future work.
