mesa: remove the fixed-func vert prog dependency on all texture states

mesa: remove the fixed-func vert prog dependency on all texture states

Just flag _NEW_FF_VERT_PROGRAM where needed. There are only a few places
that must do it.

Also do the same with _NEW_FF_FRAG_PROGRAM, but this is not sufficient
for the ff frag prog to ignore texture states.
