74268789 - Exclude test/generated_type_hints_smoketest.py from flake8 (#50497)

Exclude test/generated_type_hints_smoketest.py from flake8 (#50497) Summary: Similar to https://github.com/pytorch/pytorch/issues/48201, this PR excludes a file that is auto-generated by [`test/test_type_hints.py`](https://github.com/pytorch/pytorch/blob/5834438090a1b3206347e30968e48f44251a53a1/test/test_type_hints.py#L109-L111), which doesn't happen to be run before the Flake8 check is done in CI. Also, because the `exclude` list in `.flake8` has gotten fairly long, this PR splits it across multiple lines.
