As discussed on the development mailing list, the window list returned
by QGuiApplication::topLevellWindows() included all QWindows, even the
non top-level ones.
This commit introduces the new method allWindows(), which returns the list
of all QWindows, fixes the list returned by topLevelWindows() and also
introduces tests for both methods.
