Try to stabilize QWidget::enterLeaveOnWindowShowHide

Browse Source 
The test is very flaky on Windows 11. Make sure that we have a secondary
window to close before proceeding, and wait for fade effects to finish,
otherwise we might never get the leave event from the windowing system.

Also replace a QVERIFY(qWaitFor) construct with a simple QTRY_VERIFY.

With these changes, a local run of 20 repeats of this test on a stressed
VM improves from 75% to 100%.

Pick-to: 6.3 6.2
Fixes: QTBUG-98477
