The pass now sinks operations into a `Select` not only when non-select operands are constant, but also when the operation would simplify due to the `select_val` being a critical operand (e.g., array index, slice start, shift amount, or selector). Also replaces `LazyTernaryQueryEngine` with `PartialInfoQueryEngine` in `StrengthReductionPass`. PiperOrigin-RevId: 822621831
