zlib-ng-2.1.x supports AVX512VNNI. We don't have a CPU_FLAGS_X86_ flag for it right now, so I can't wire it up in the ebuild. I don't know if cpuid2cpuflags properly detects it as I don't have any HW for it. We could try Intel's SDE which I found easy to setup to test it? (Maybe even add it to CI for cpuid2cpuflags).
Need VPCLMULQDQ too, which is separate.
