Enable additional authentication mechanisms in librdkafka

[rockwood-openai]

The main reasons from what I can tell for enabling SSL or CURL is to also be able to enabled additional authentication mechanisms

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

The title says 'add additional dependencies' but I don't see any dependency changes here. Did you forget to commit vcpkg.json changes?

[BillyONeal]

Existing versions must not be changed. Please revert changes to this file, set port-version in vcpkg.json to 1, and rerun vcpkg x-add-version. (There should only be a new version here added to the top, not overwriting an existing version)

Please feel free to mark 'ready for review' when you're ready for another review :)

I mean it adds the additional opt-in auth plugins to librdkafka, I've updated the PR title. Thanks!
