Fix various small documentation errors

Fix missing transfer annotations, remove old syntax from gtk-doc, correct an `element-type` annotation, and fix a typo.

Testing Done:
Compiled with docs on, and got fewer warnings. Also functions with added transfer annotations are no longer unavailable to bindings.
