[ONNX] Remove the last Cast in pow symbolic_opset9 (#52646) (#53305) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/53305 Fixes #52436 For opset 9 of onnx Pow, if X is int32, Y is float, we will cast back to int32 which is consistent with X type. However, pytorch is still float. The aten graph sometimes does not bind with the type for operators, we are fine with the float type and don't want to cast back. Even if X, Y are int32, the resulting float32 and int32 makes no difference.
