QMetaType: Expand and clean up converter/view function documentation

This adds a few snippets to show how the functions can be used, and also
removes workarounds for oldver versions of qdoc that weren't clang based
- those workarounds also seem to have caused some bitrot.

Remove documentation for an overload of registerMutableView that
currently does not exist (for a member function with an ok parameter).

Fixes: QTBUG-96963
Pick-to: 6.2
