Remove log depth reduction terms. Motivated by the elo loss of last VVLTC regression test i remove the new log depth reductions (tuned at STC) to regain strength at VVLTC. The constant terms are adjusted based on the old values and the changes from the last added VVLTC tuning. Passed VVLTC with STC bound: LLR: 2.95 (-2.94,2.94) <0.00,2.00> Total: 53802 W: 14030 L: 13740 D: 26032 Ptnml(0-2): 5, 4924, 16754, 5212, 6 https://tests.stockfishchess.org/tests/view/68a9a9f575da51a345a5a675 Passed VVLTC with LTC bound: LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 53658 W: 14022 L: 13699 D: 25937 Ptnml(0-2): 3, 4894, 16712, 5217, 3 https://tests.stockfishchess.org/tests/view/68a8d2b2b6fb3300203bca77 closes https://github.com/official-stockfish/Stockfish/pull/6257 Bench: 2566780
