PyO3 0.21.2

This release contains some fixes to compile-time edge cases for the PyO3 0.21 series:

• A missing deprecation warning for the GIL Ref constructor PySet::empty has now been added.
• #[pymodule] functions will no longer trigger missing_docs lints on their generated code.
• Incorrect implementations of __traverse__ in #[pymethods] will now emit a better error.
• Extension modules on AIX will now link to libpython.

This release also fixes some compile errors for the experimental-async and experimental-declarative-modules features, and corrects some documentation typos.

Thank you to the following users for the improvements:
