Remove custom mutex implementation As part of the investigation of the hang caused by an incorrect implementation of condition_variable in libwinpthread, it was realized that our custom Mutex implementation is no longer needed. Prior to lazySMP this custom implementation resulted in a 30% speedup, but now no speed difference can be measured as no mutex is used on the hot path in lazySMP. https://github.com/official-stockfish/Stockfish/issues/2291 https://github.com/official-stockfish/Stockfish/issues/2309#issuecomment-533733393 https://github.com/official-stockfish/Stockfish/issues/2309#issuecomment-533737515 The interest of this patch is that it removes platform-specific code, which is always less tested. No functional change.
