st/nine: sm1_declusage_to_tgsi, do not restrict indices with TGSI_SEMANTIC_GENERIC

Browse Source 
With sm3, you can declare an input/output with an usage and an usage index.

Nine code hardcodes the translation usage/index to a corresponding TGSI code.
The translation was limited to a few usage/index combinations that were corresponding
to most of the needs of games, but some games did not work.

This patch rewrites that Nine code to map all possible usage/index combination
to TGSI code. The index associated to TGSI_SEMANTIC_GENERIC doesn't need to be low
for good performance, as the old code was supposing, and is not particularly bounded
(it's UINT16). Given the index is BYTE, we can map all combinations.
