QQmlDelegateModelItem: move row and column up to the base class

Change 8c33c70 injected row and column (alongside index) into
the QML context of a delegate when the view had a
QAbstractItemModel as model.

Rather than only inject those properties when using QAIM, this patch
will move the code to the base class. This way, if a view uses e.g
a javascript list as model, row and column is still be available. This
is useful, since then the delegate can bind to both row and column
regardless of what kind of model the view uses. In the case of a
list model, the column property will always be 0.
