[JIT] Infer NamedTuple type attributes of nn.Modules correctly (#39116) Summary: **Summary** This commit modifies type inference for `nn.Module` instance attributes such that the type of a `NamedTuple` attribute is inferred correctly and such that the field names of this `NamedTuple` instance can be used in scripted methods. At present, the type of this attribute is inferred to be `Tuple[T, U, ..., V]`, so the field must be referred to by index and cannot be referred to by name. **Test Plan** This commit adds a unit test to test that a field of a `NamedTuple` attribute can be referred to by name in a scripted method. **Fixes** This commit fixes https://github.com/pytorch/pytorch/issues/37668.
