Accumulator cache bugfix and cleanup STC: https://tests.stockfishchess.org/tests/view/663068913a05f1bf7a511dc2 LLR: 2.98 (-2.94,2.94) <-1.75,0.25> Total: 70304 W: 18211 L: 18026 D: 34067 Ptnml(0-2): 232, 7966, 18582, 8129, 243 1) Fixes a bug introduced in https://github.com/official-stockfish/Stockfish/pull/5194. Only one psqtOnly flag was used for two perspectives which was causing wrong entries to be cleared and marked. 2) The finny caches should be cleared like histories and not at the start of every search. closes https://github.com/official-stockfish/Stockfish/pull/5203 No functional change
