[TensorExpr] Fix handling of 0-dim tensors. (#59279)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/59279
There were some issues with how we handle 0-dim cases in lowerings and
also in how we generate reductions in that special case. This PR fixes
those issues and reenables a bunch of tests.
