This change introduces several helper functions to be used in the upcoming `PropagateQSVPass`. These functions provide core utilities for inspecting and manipulating quantization operations in the MLIR graph. The new functions include: - `IsProducedByDQ`: Checks if a value is the result of a `DequantizeOp`. - `IsDefiningQ`: Checks if a value's only use is a `QuantizeOp`. - `InsertQDQ`: Inserts a `QuantizeOp`/`DequantizeOp` pair for a given value. These helpers are essential for the logic in `PropagateQSVPass`, which will handle the propagation of quantization parameters. PiperOrigin-RevId: 787306700
