[enhancement]: fix typing of untyped-defs

# Enhancement

In https://github.com/canonical/cloud-init/pull/5409 we enabled the `check_untyped_defs` mypy lint to not include more type issues and disabled modules not passing the check. Fix them all!

If you want to work any of the modules listed below, please add a comment with the name of the module you are working on so that work isn't duplicated.
