Add QVariant container iteration API.
A new set of classes is introduced for iterating over the contents
of a container within a QVariant without knowing the exact type of
the container, but with the guarantee that the element type within
the container is a metatype.
The implementation of the iterable interface uses
the stl-compatible container API so that we can also iterate over stl
containers, or any other container which also conforms to stl norms.
This enables the functionality in the bug report.
Task-number: QTBUG-23566
