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.

The helper function TestWidget::waitForPainted returned after the test
widget had consumed the first paint event. In case of multiple paint
events, QRegion paintedRegions did not match the entire region that
was supposed to be painted. The test function children() failed/flaked
due to that.
This patch extends the helper function. After consumption of the first
paint event, it processes events until the painted regions no longer
change.

Expose QWidgetRepaintManager's data structures so that we can write
unit tests, and verify that they are correct after moving opaque
widgets (which triggers the accelerated move code path).
Improve the compareWidget logic to not rely on screen grabbing
(which requires permissions), but instead use QPlatformBackingStore's
toImage function, which is faster and more reliable, and also doesn't
require us to show the UI we want to grab full screen in order to
avoid issues with overlapping windows etc.

Added to QWidgetRepaintManager test case, which is the only place where
the function is used.
Includes a helper that creates a complex scene with opaque children,
which will be used in additional unit tests.

In paintAndFlush, QWidgetRepaintManager subtracts opaque children if
the target isn't overlapped and isMoved is set to true. So in moveRect,
set isMoved to true after the blitting of movable areas, and reset it to
false if we have overlapped sibling or child regions. Otherwise, moving
so far that sourceRect is invalid (none of the original pixels are
visible after the move) we end up in a code path that sets isMoved to
true even with overlapping children or siblings, which then breaks
paintAndFlush's assumptions.
Reuse the test case written by Sergiy Korobov <tiamatenko@gmail.com> in
earlier attempts to fix this bug.
