Reduce SIMD register count from 32 to 16 in the case of avx512 and vnni512 archs. Up to 17% speedup, depending on the compiler, e.g. ``` AMD pro 7840u (zen4 phoenix apu 4nm) bash bench_parallel.sh ./stockfish_avx512_gcc13 ./stockfish_avx512_pr_gcc13 20 10 sf_base = 1077737 +/- 8446 (95%) sf_test = 1264268 +/- 8543 (95%) diff = 186531 +/- 4280 (95%) speedup = 17.308% +/- 0.397% (95%) ``` Prior to this patch, it appears gcc spills registers. closes https://github.com/official-stockfish/Stockfish/pull/4796 No functional change
