Do more aggressive futility pruning for captures This patch lines up with other patches which use better eval to produce more aggressive cutoffs based on static evaluation of position, it allows more aggressive futility pruning for captures - so now we will be producing them with bigger evaluation of position, so more often. passed STC https://tests.stockfishchess.org/tests/view/5f2da79e61e3b6af64881fd2 LLR: 3.87 (-2.94,2.94) {-0.50,1.50} Total: 27256 W: 3809 L: 3593 D: 19854 Ptnml(0-2): 221, 2578, 7830, 2762, 237 passed LTC https://tests.stockfishchess.org/tests/view/5f2df92061e3b6af64882012 LLR: 4.97 (-2.94,2.94) {0.25,1.75} Total: 43624 W: 3095 L: 2820 D: 37709 Ptnml(0-2): 66, 2410, 16608, 2639, 89 closes https://github.com/official-stockfish/Stockfish/pull/2946 Bench: 4272280
