Simplify usage of LMR for captures This patch simplifies a lot of "enablers" for LMR when move is a capture or promotion. After it we will have only 2 conditions - if node is a cutNode or if it's an allNode that was not in PV, so all captures or promotions wouldn't go thru LMR at any PVnodes. passed STC https://tests.stockfishchess.org/tests/view/60a40117ce8ea25a3ef03ca7 LLR: 2.95 (-2.94,2.94) <-2.50,0.50> Total: 58976 W: 4875 L: 4807 D: 49294 Ptnml(0-2): 176, 3897, 21270, 3973, 172 passed LTC https://tests.stockfishchess.org/tests/view/60a43ff8ce8ea25a3ef03d18 LLR: 2.93 (-2.94,2.94) <-2.50,0.50> Total: 65272 W: 2203 L: 2165 D: 60904 Ptnml(0-2): 28, 1936, 28668, 1978, 26 closes https://github.com/official-stockfish/Stockfish/pull/3480 bench 4110764
