* Fix model load exception when state resides on GPU

- Whenever converting a torch.tensor to numpy, we need to first
migrate the tensor storage to the host CPU.

- Add a warning not to do contant-folding when exporting to ONNX.
This is due to a torch.onnx export bug.

- Refactor compare_outputs

* Add a temporary workaround to layernorm export

Seems like ORT is performing template-matching for LN and incorrectly concludes
that it doesn't have a kernel for FP32 LN. The work-around adds the addition of
fake_zero which is meant to prevent the template matching while keeping the graph
virtually unchanged. This also requires `do_constant_folding=False` in
`torch.onnx.export`.

2. The TE kernels are not changed, the diff should come from
   new codegen behavior of XLA.
