Disable AVX512 on Darwin (#13550) 

Preemptively disable AVX512 until https://github.com/golang/go/issues/49233 has been resolved.

This potentially affects reedsolomon, simdjson, sha256-simd, md5-simd packages.

Init order requires a separate package since main itself is initialized last, but imports are initialized in the order they are imported from main (confirmed).
