RFR: 8351412: Add AVX-512 intrinsics for ML-KEM [v3]

Mon May 12 08:57:36 UTC 2025

> By using the AVX-512 vector registers the speed of the computation of the ML-KEM algorithms (key generation, encapsulation, decapsulation) can be approximately doubled.

Ferenc Rakoczi has updated the pull request incrementally with one additional commit since the last revision:

  Eliminating some instructions from generate_kyber12To16_avx512() + fixing a comment.
