Adjust schemas of a couple prims (#82821)
For context: https://github.com/pytorch/pytorch/issues/82763
I spent a bit of time trying to get a test working here but it's kind of tricky because some primtorch refs correspond to multiple schemas. I think ultimately what we want is something like the [backwards compatibiliity](https://github.com/pytorch/pytorch/blob/master/aten/src/ATen/core/function_schema_inl.h#L187) check but with checking the prim signatures against aten signatures.
These signatures compatibility should also be tested through FakeTensors, although the `nan_to_num` bug was not tested because of https://github.com/pytorch/pytorch/issues/82785.
