Simplify capture pruning margin formula Using just `PawnValueEg * depth` as Capture Prune Margin. There was a bunch of patches that passed recently regarding captures, maybe this part of the master code redundant? The patch was tested as a simplification: STC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 20833 W: 4218 L: 4096 D: 12519 http://tests.stockfishchess.org/tests/view/5b1cf2100ebc5902ab9c6651 LTC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 27050 W: 3975 L: 3864 D: 19211 http://tests.stockfishchess.org/tests/view/5b1cfdc80ebc5902ab9c6776 Closes https://github.com/official-stockfish/Stockfish/pull/1643 Bench: 4980482
