fix LTC usage of torch.tensor ctr, add test (#81928)
switching the tensor constructor to use `lift_fresh` instead of `lift` silently broken LTC, because we didn't have a test for it. I added one here.
The fix is that LTC now also needs a kernel for `lift_fresh`.
The way this error manifests is that if you call `torch.tensor(..., device='lazy')`, we expect the result to be wrapped up a functional wrapper, and it wasn't - so calling any view ops on the tensor will now break. That wrapping is supposed to happen in `lift_fresh` now.
