Stabilize tst_QWidgetRepaintManager on XCB platforms
When a widget's palette has different brushes in Active / Inactive
color groups, or it is pixmap based, multiple paint events are
triggered. This leads to unpredictable, double entries in
QWidgetRepaintManager::dirtyWidgetList().
This patch overrides event() of all test widgets and ignores
activation / deactivation events in order to make the entries of
QWidgetRepaintManager::dirtyWidgetList() predictable.
Pick-to: 6.4
