Improve Speedtest Speed Timing This tries to make the timing of the search function to be a bit more precise and start the timing at the start and right when the bestmove is send and thus avoids including any logic which happens in between (network verification, thread awakening etc.). It also keeps the timepoint in chrono for the duration of the benchmark and converts to milliseconds only at the end. closes https://github.com/official-stockfish/Stockfish/pull/7002 No functional change
