shiboken6: Store AbstractMetaFunction using a QSharedPointer

Store the list functions (global / class member) as a
QList<QSharedPointer<const AbstractMetaFunction> instead of a raw
pointer list. This makes passing around function lists easier and
solves the memory leaks caused by mixing cloned and unmodified
functions while collecting the overload lists in the generators.

- Change the function signatures accordingly
- Add a qSharedPointerConstCast() for non-const access.
- Restructure the traversing of added functions
  in the AbstractMetaBuilder
- Remove some unused typedefs and functions unearthed by
  the change
