Drop ABI=9 Support
This drops ABI=9 support in preparation for VDB 12.0, but keeps the version as 11.x for the time being.
This also edits the deprecation document to accurately reflect the change in policy around when to remove support for obsolete ABIs.
(I decided to make this a feature branch and rebase it on top of the CI updates, so I can build other changes against it and validate the CI).
