This is follow-up of #165037. It generally recommended to use `is/is not` to compare types. Therefore this series of changes apply this suggestion in the code base, and it aims to finally enabling related linter checks.

Changes in details:
- Fix and update some out-of-date type hints in `_functorch/make_functional.py`.
- ~Explicitly use `OrderedDict` for order-sensitive mappings.~
In `create_names_map()`, `_swap_state()`, and `FunctionalModuleWithBuffers.__init__()`, the unordered `dict` was used. The key order should be preserved for `dict.items()` while it is required to `zip` with a tuple of `params`/`buffers`. Although since Python 3.6, the built-in dictionary is insertion ordered ([PEP 468](https://peps.python.org/pep-0468)). Explicit is better than implicit.

This will be the last disruptive functorch internals change.
Why are we moving these files?
- As a part of rationalizing functorch we are moving the code in
functorch/_src to torch/_functorch
- This is so that we can offer the functorch APIs as native PyTorch APIs
(coming soon) and resolve some internal build issues.
Why are we moving all of these files at once?
- It's better to break developers all at once rather than many times
Test Plan:
- wait for tests
