[ONNX] Add support for calling tensor.to(tensor.device).

[fatcat-z]

Currently, if we call tensor.to() method and pass a device as the parameter. It will fail, because in symbolic function of to() we didn't handle such case.

So add a check in the beginning of this symbolic function, if this is a device cast, we return self directly. A test has also been added.
