Fix for profile-build failure using gcc on MacOS
Fixes https://github.com/official-stockfish/Stockfish/issues/3846 ,
where the profiling SF binary generated by GCC on MacOS would launch
but failed to quit. Tested with gcc-8, gcc9, gcc10, gcc-11.
The problem can be fixed by adding -fvisibility=hidden to the compiler
flags, see for example the following piece of Apple documentation:
https://developer.apple.com/library/archive/documentation/DeveloperTools/Conceptual/CppRuntimeEnv/Articles/SymbolVisibility.html
For instance this now works:
make -j8 profile-build ARCH=x86-64-avx2 COMP=gcc COMPCXX=g++-11
No functional change

Remove lowPly history
Seems that after pull request #3731 (Capping stat bonus at 2000) this
heuristic is no longer useful.
