Rong Rong (AI Infra) 26beda8ed5 [BE] unsupported backward failing on single sample (#59455) 
Summary:
Echo on https://github.com/pytorch/pytorch/pull/58260#discussion_r637467625

similar to `test_unsupported_dtype` which only check exception raised on the first sample. we should do similar things for unsupported_backward as well. The goal for both test is to remind developer to
1. add a new dtype to the support list if they are fulling runnable without failure (over all samples)
2. replace the skip mechanism which will indefinitely ignore tests without warning

Pull Request resolved: https://github.com/pytorch/pytorch/pull/59455

Test Plan: CI.

() - single input,
(0,) - zero batched dimension,
(2,) - batch of two matrices.
'ns' gives 0x0 and 5x5 matrices.
and 'nrhs' controls the number of vectors to solve for:
() - using 1 as the number of vectors implicitly
(1,) - same as () but explicit
(3,) - solve for 3 vectors.
Zeros in dimensions are edge cases in the implementation and important to test for in order to avoid unexpected crashes.
'vector_rhs_allowed' controls whether to include nrhs = () to the list of SampleInputs.
torch.solve / triangular_solve / cholesky_solve (opposed to torch.linalg.solve) do not allow
1D tensors (vectors) as the right-hand-side.
Once torch.solve / triangular_solve / cholesky_solve and its testing are removed,
'vector_rhs_allowed' may be removed here as well.
