Expose the lazy threshold for the feature transformer PSQT as a parameter. Definition of the lazy threshold moved to evaluate.cpp where all others are. Lazy threshold only used for real searches, not used for the "eval" call. This preserves the purity of NNUE evaluation, which is useful to verify consistency between the engine and the NNUE trainer. closes https://github.com/official-stockfish/Stockfish/pull/3499 No functional change
