MDEV-33817: AVX-512 based CRC-32

This is based on https://github.com/intel/intel-ipsec-mb/
and not yet tested. GCC 11 or clang 8 or later should be able to compile
this, hopefully also MSVC.

TODO: Test and clean up the code further. Some variable names
try to correspond to the register names in
intel-ipsec-mb/lib/avx512_t2/crc32_by16_vclmul_avx512.asm
(note: the 128-bit AVX XMM registers alias
the 256-bit AVX YMM registers, which alias the AVX-512 ZMM registers)
