Rebalance usage of history heuristics in pruning This patch has multiple effects: * history heuristics sum in futility pruning now can't exceed some negative value so futility pruning for moves with negative histories should become slightly less aggressive; * history heuristics are now used in SEE pruning for quiet moves; Passed STC: https://tests.stockfishchess.org/tests/view/63cde339c93e8828d0f02e3a LLR: 2.94 (-2.94,2.94) <0.00,2.00> Total: 88424 W: 23681 L: 23303 D: 41440 Ptnml(0-2): 258, 9559, 24219, 9899, 277 Passed LTC: https://tests.stockfishchess.org/tests/view/63ce9009c93e8828d0f04e4f LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 79536 W: 21223 L: 20843 D: 37470 Ptnml(0-2): 22, 7599, 24146, 7979, 22 closes https://github.com/official-stockfish/Stockfish/pull/4355 Bench: 4208265
