fa4cab89 - [Sparse] Raise exception when expand is called on sparse tensor (#98365)

[Sparse] Raise exception when expand is called on sparse tensor (#98365) It's already not working, but this makes error message a bit more readable. I.e. it turns: ``` % python -c "import torch;x=torch.eye(3).to_sparse().expand(3,3)" ``` from ``` NotImplementedError: Could not run 'aten::as_strided' with arguments from the 'SparseCPU' backend. ``` to ``` RuntimeError: Expand is unsupported for Sparse tensors. ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/98365 Approved by: https://github.com/pearu, https://github.com/cpuhrsch
