Fix avx512icl update_piece_threats bug Thanks to MinetaS for discovering this and finding the culprit commit, specific to this architecture. 9f42980 was subtly incorrect, leading to spurious wrong benches on avx512icl. Because this piece of code has twice been the source of wrong benches, I also added a brief comment explaining why it needs to be this way, and added a sample position to bench. closes https://github.com/official-stockfish/Stockfish/pull/6654 Bench: 2288704
