gallium: no need to keep a copy of shader tokens in state tracker

Any driver who needs a copy of the shader tokens must organize to
do so itself.  This has been the case for a long time, but there
was still defensive code in the state tracker, which is now removed.

Any bugs resulting from this need to be fixed in the offending driver...
