fix syzygy crash on Apple Silicon by unrolling tbprobe adjustment loop A bit tricky to identify, but in `apple-silicon` builds, specifying a value for `SyzygyPath` could still lead to crashes at certain depths from a SIGBUS/SIGSEGV. This PR replaces the `std::count_if()` adjustment in `tbprobe.cpp`'s `do_probe_table()` with an annotated handwritten loop, avoiding the clang/LTO miscompilation behind the crash. closes https://github.com/official-stockfish/Stockfish/pull/6721 No functional change.
