André de la Rocha 4114a0ea75 Windows QPA: Fix slowdown with large table/tree views with accessibility 
The accessibility code for notifying focus changes related to a
table/tree view was iterating over all items to find the focused one,
which for a very large number of items could cause a major slowdown
and UI freeze. This patch avoids the issue by removing the loop and
implementing the focusChild() method in the table/tree accessibility
classes.

Fixes: QTBUG-100997
Pick-to: 6.2 6.3 5.15
