mesa: remove GLvertexformat

Function pointers were first set in GLvertexformat, and then
GLvertexformat was copied to the dispatch.

This just sets the function pointers in the dispatch directly,
skipping the intermediate GLvertexformat structure.

The code with SET_* calls is autogenerated by api_vtxfmt_init_h.py.
