stop creating integer type Tensors that require gradients (#37789)
Summary:
Fix https://github.com/pytorch/pytorch/issues/37680
Makes two changes:
- Add `argmin`, `argmax` and `argsort` to the list of non-differentiable functions to prevent them from generating outputs that requires_grad.
- Add a check to make sure we don't add such functions to the codegen by mistake.
