[mlir][tosa] Change ClampOp's min/max attributes (llvm#125197)
This changes Tosa ClampOp attributes to min_val and max_val which are either integer attributes or float attributes, and adds verify checks that these attribute element types must match element types of input and output Co-authored-by: Tai Ly <[email protected]>
