freedreno/a6xx: re-arrange program stageobj/group 

Split out a separate program config state group to run early before the
other groups.

This seems to help w/ intermittent "missed tiles" (although I had
assumed that was a mem2gmem issue), or at least I can't reproduce that
issue with this patch, but can without.

It has the benefit of HLSQ_VS_CNTL.CONSTLEN matching for VS and BS.
