Resolve NamedTuple types in Python (#26443)
Summary:
When used as annotations on Python functions, `NamedTuple`s go through our Python annotation -> type mapping which previously had no way of lookup up `NamedTuple`s (which are created lazily by checking if the type has certain properties, so the lookup is creating the `TupleType` from scratch). This PR threads through the necessary data to make them work.
Fixes #26437
