Move the engine options into the engine class, also avoid duplicated initializations after startup. UCIEngine needs to register an add_listener to listen to all option changes and print these. Also avoid a double initialization of the TT, which was the case with the old state. closes https://github.com/official-stockfish/Stockfish/pull/5356 No functional change
