Test for QWindow getting enter/leave events when secondary window shows/hides

Browse Source 
Equivalent to the test added to the QWidget test case, but since QtWidgets
code contains logic to both synthesize and compress/filter enter/leave
events, we can only verify that the QWindow does get the events.

The test is very flaky on Windows, so blacklisting it right away.

Verify that we get enter and leave events if the window under the mouse
opens and closes a modal dialog or popup. QWindow might get multiple
events in a row, as the various QPA plugins need to use different techniques
to synthesize events if the native platform doesn't provide them for us.
