Remove x86-64-vnni256 target When vnni256 was first introduced #3038 it was very slightly faster than vnni512 on some machines. We have since sped up vnni512 significantly (#4796 over 10% alone, #6139, and probably others I'm forgetting). Since any machine that can run vnni256 can run vnni512 this arch is no longer useful. Note, x86-64-avxvnni still covers targets that don't have AVX512 but do have VNNI on 128- and 256-bit vectors. closes https://github.com/official-stockfish/Stockfish/pull/6340 No functional change
