Accessibility: childAt returns interface
childAt used to return an integer.
Return an interface instead.
Not requiring a direct child to be returned allows optimizing
by bypassing iterating through the hierarchy of accessibles.
For QtQuick this is the only sensible way of implementing this.
The bridges are still responsible for finding the top-most element.
The default implementation in QAccessibleObject is sufficient
to return direct children. The implementation in
QAccessibleApplication is therfore no longer needed.
