For indexing, we use the existing threats feature set by adding the forward square to the squares threatened by a pawn. This threat is only enabled when another pawn occupies that square. We then add appropriate logic changes in `update_piece_threats` and `features/full_threats.cpp`. The wonderful Ciekce (of Stormphrax) and peregrine (of Reckless) also had similar ideas with adding forward pawn movements to TI, and I appreciate their giving me motivation to figure out `nnue-pytorch` and test it. closes https://github.com/official-stockfish/Stockfish/pull/6694 Bench: 2926703
