Accessibility Mac: Fix handling of top level widget

This simplifies how we handle QNSView for accessibility purposes.
Instead of trying to half-merge the top level widget
(window->accessibleRoot) into the view, just have the view
always return it as child.
This makes the accessibility implementation for QNSView simpler
and makes applications that show a top level widget such as a button
possible. (We would return accessibility ignored for the button before).

As a side effect finding the active focus and hit-testing should be more reliable as
well.
Task-number: QTBUG-37794
