Simplify limiting extensions. Replace the current method for limiting extensions to avoid search getting stuck with a much simpler method. the test position in https://github.com/official-stockfish/Stockfish/commit/73018a03375b4b72ee482eb5a4a2152d7e4f0aac can still be searched without stuck search. fixes #3815 where the search now makes progress with rootDepth shows robust behavior in a d10 search for 1M positions. passed STC https://tests.stockfishchess.org/tests/view/61e303e3babab931824dfb18 LLR: 2.94 (-2.94,2.94) <-2.25,0.25> Total: 57568 W: 15449 L: 15327 D: 26792 Ptnml(0-2): 243, 6211, 15779, 6283, 268 passed LTC https://tests.stockfishchess.org/tests/view/61e3586cbabab931824e091c LLR: 2.96 (-2.94,2.94) <-2.25,0.25> Total: 128200 W: 34632 L: 34613 D: 58955 Ptnml(0-2): 124, 12559, 38710, 12588, 119 closes https://github.com/official-stockfish/Stockfish/pull/3899 Bench: 4550528
