Ryan LefkowitzandJoost VandeVondele bb5f0100b0 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.
