Remove duplicated Position object in UCIEngine Also fixes searchmoves. Drop the need of a Position object in uci.cpp. A side note, it is still required for the static functions, but these should be moved to a different namespace/class later on, since sf kinda relies on them. closes https://github.com/official-stockfish/Stockfish/pull/5169 No functional change
