Remove the Contempt UCI option This patch removes the UCI option for setting Contempt in classical evaluation. It is exactly equivalent to using Contempt=0 for the UCI contempt value and keeping the dynamic part in the algo (renaming this dynamic part `trend` to better describe what it does). We have tried quite hard to implement a working Contempt feature for NNUE but nothing really worked, so it is probably time to give up. Interested chess fans wishing to keep playing with the UCI option for Contempt and use it with the classical eval are urged to download the version tagged "SF_Classical" of Stockfish (dated 31 July 2020), as it was the last version where our search algorithm was tuned for the classical eval and is probably our strongest classical player ever: https://github.com/official-stockfish/Stockfish/tags Passed STC: LLR: 2.95 (-2.94,2.94) <-2.50,0.50> Total: 72904 W: 6228 L: 6175 D: 60501 Ptnml(0-2): 221, 5006, 25971, 5007, 247 https://tests.stockfishchess.org/tests/view/60c98bf9457376eb8bcab18d Passed LTC: LLR: 2.93 (-2.94,2.94) <-2.50,0.50> Total: 45168 W: 1601 L: 1547 D: 42020 Ptnml(0-2): 38, 1331, 19786, 1397, 32 https://tests.stockfishchess.org/tests/view/60c9c7fa457376eb8bcab1bb closes https://github.com/official-stockfish/Stockfish/pull/3575 Bench: 4947716
