[ref model] Change PadOp's padding to Shape

Changed to use pad input of PadOp for testing.
The pad input is now a tensor of tosa.shape type.

moved padding error checking from checkTensorAttributes to eval
modified pad's PadOutputShapeMismatch test generation to avoid
generating output shapes with dimensions <= 0
