Commit ID beb327f910ed782f358d69201643ccd99b982a48

Fix a Windows-only crash on exit without 'quit' There was a bug in commit d4763424d2728fe2dfd0a6fe747666feb6a2fdbb (Add support for Windows large pages) that could result in trying to free memory allocated with VirtualAlloc incorrectly with free(). Fix this by reverting the TT.resize(0) logic in the previous commit, and instead, just call aligned_ttmem_free() in TranspositionTable::~TranspositionTable(). fixes https://github.com/official-stockfish/Stockfish/issues/2677 closes https://github.com/official-stockfish/Stockfish/pull/2679 No functional change
