Correctly output lowerbound/upperbound in threaded searches fixes the lowerbound/upperbound output by taking the alpha,beta bracket into account also if a bestThread is selected that is different from the master thread. Instead of keeping track which bounds where used in the specific search, in this version we simply store the quality (exact, upperbound, lowerbound) of the score along with the actual score as information on rootMove. closes https://github.com/official-stockfish/Stockfish/pull/4239 No functional change
