Optimize find_nnz() using AVX512 About a 1% speedup for ARCH x86-64-avx512 and x86-64-vnni512. Note: This could be optimized further if we wanted to add an ARCH supporting VBMI2 which is even more modern than VNNI. https://en.wikichip.org/wiki/x86/avx512_vbmi2 closes https://github.com/official-stockfish/Stockfish/pull/6139 No functional change
