Assert correct MaxChunkSize at compile time If for example you change MaxChunkSize from 64 to 32 or 128 for an avx512 build it compiles fine but you get a crash or a wrong bench respectively when running the binary. This static assert catches the issue at compile time. closes https://github.com/official-stockfish/Stockfish/pull/7193 No functional change
