xdg-shell v5,v6 shell integrations: Fix crash when showing popups
If a popup was shown without any input events happening first, it would cause
nullptr dereferences in both xdg-shell v5 and v6.
Fixes crashes in:
- tst_QAccessibility::comboBoxTest
- tst_QAccessibility::menuTest
- tst_QWindow::touchInterruptedByPopup
- tst_QFocusEvent::checkReason_Popup
Task-number: QTBUG-67150
