This is a refactor of https://github.com/official-stockfish/Stockfish/pull/6766 so we don't have to include nnue_architecture.h
It also includes the fix in https://github.com/official-stockfish/Stockfish/pull/6769 which was needed to make this work.
mstembera made rhirsch123 the author. credits also to anematode.
[Edit] Also fixes a bug where _mm512_packus_epi32 was being used instead of the correct _mm512_packs_epi32 for the IceLake version.
