[JIT] Add special cases for batch_norm, instance_norm in alias_analysis (#66554)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/66554
In native_functions.yaml, the schemas for batch_norm and instance_norm
are incorrect: the inputs `running_mean` and `running_var` are mutated,
but are not marked as such in the function schema. Since `(a!)?`
annotations are currently not working (see #65760), this instead adds a
special case to `alias_anaysis.cpp`. If the value of `training` or
`use_input_stats` is known to be `false`, then `alias_analysis` will
mark the input as _not_ being written to.
Test Plan:
Removed the `skip` annotation on the following test, and added a special
exception in `check_alias_annotations`:
```
python test/test_ops.py -k test_variant_consistency_jit_nn_functional_batch_norm
```
Also:
```
./build/bin/test_jit --gtest_filter="*BatchAndInstanceNormFixture*"
```
