Test 0->0 correspondence for Unary Ops with Sparse CSR inputs (#70302)
Summary:
Since there is no rule in PyTorch (Sparse CSR) for filling zeros, it was decided that only those ops will be supported which do not break 0->0 correspondence. To ensure that this rule is not broken, this PR aims to add a test to ensure this rule is not broken.
`sample_inputs_unary` may or may not generate a zero in the sample input. Hence, this separate test is good for validating the rule, and the support for Sparse CSR.
