8695f0cc - Rectify `native_batch_norm` schema by splitting it into two legit schemas (#88697)

Rectify `native_batch_norm` schema by splitting it into two legit schemas (#88697) Using the same repro from the issue (but with BatchNorm2D) Rectifies native_batch_norm schema by splitting the schema into 2: 1. one will have NON-optional alias-able running_mean and running_var inputs 2. the other will just not have those parameters at all (no_stats variation) **Calling for name suggestions!** ## test plan I've added tests in test_functionalization.py as well as an entry in common_method_invocations.py for `native_batch_norm_legit` CI should pass. ## next steps Because of bc/fc reasons, we reroute native_batch_norm to call our new schemas ONLY through the python dispatcher, but in 2 weeks or so, we should make `native_batch_norm_legit` the official batch_norm.
