Support VNNI on 256bit vectors due to downclocking on current chips (tested up to cascade lake) supporting avx512 and vnni512, it is better to use avx2 or vnni256 in multithreaded (in particular hyperthreaded) engine use. In single threaded use, the picture is different. gcc compilation for vnni256 requires a toolchain for gcc >= 9. closes https://github.com/official-stockfish/Stockfish/pull/3038 No functional change
