Fixed UCI TB win values This patch results in search values for a TB win/loss to be reported in a way that does not change with normalization, i.e. will be consistent over time. A value of 200.00 pawns is now reported upon entering a TB won position. Values smaller than 200.00 relate to the distance in plies from the root to the probed position position, with 1 cp being 1 ply distance. closes https://github.com/official-stockfish/Stockfish/pull/4353 No functional change
