Make some QAbstractItemModel API invokable

As QAIM and related classes are becoming more useful in the QML
environment, it makes sense to make these invokable.

Make the access API and the setData method scriptable.  Avoid
making the structure changing APIs scriptable now to be conservative.

Export the ItemDataRole enum through the staticQtMetaObject to make
built-in roles available.
