Add NumaPolicy "hardware" option that bypasses current processor affinity. Can be used in case a GUI (e.g. ChessBase 17 see #5307) sets affinity to a single processor group, but the user would like to use the full capabilities of the hardware. Improves affinity handling on Windows in case of multiple available APIs and existing affinities. closes https://github.com/official-stockfish/Stockfish/pull/5353 No functional change
