QList: prepare for tag dispatching based on memory layout
Add one tag class for each of QList's three different memory layouts
to QListData, and inherit QList<T>::MemoryLayout from exactly one of
them.
To simplify overloading, added tag classes that express the negation
of the two extreme poles of memory layout (C-compatible and heap),
too. The "missing" one could be added when needed, too.
