Android A11Y: Notify android about scroll events
QtQuick Flickable has an issue that after a scroll the previously
hidden items are not added to the A11Y hierarchy. That happens because
Android has no ways to detect that something has changed.
This patch uses the ScrollingEnd event to notify Android A11Y backend
that the Flickable was scrolled, so that it could update the A11Y
hierarchy and add the previously hidden nodes.
The ScrollingEnd event generation is added to QQuickFlickable in a
separate commit.
Task-number: QTBUG-103513
