The big change is that we now keep the id objects representing accessibles
around so that they are persistent for ATs.
This improves performance of Mac accessibility significantly.
This is required for notifications which are now sent so that many things work much better,
for example the VoiceOver focus follows the keyboard focus.
The parent element in QCocoaAccessibleElement was removed, we can
dynamically access it more reliably.

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.

On Mac it's expected that some elements are
filtered out of the a11y hierarchy.
We do this with the shouldBeIgnored function.
The problem is that we would ignore some objects
and then return them in the child attribute function.
This is inconsistent and leads to voice over not working.
For example having a plain QWidget with other widgets as
children would cut off all of these widgets, since the
plain QWidget would be ignored.
