doc: Revert to documenting the actual functions

A few member functions of QCborValue and QCborValueRef were given special
declarations for qdoc to see so that they could be documented as a single
function, but because clang is now used to parse c++, the special declarations
caused parsing errors.

The declarations for qdoc are removed in this update, but the functions are
still documented with a single comment by grouping the \fn commands for the
similar functions together in the single comment.
