Fix memory leak in some plasma components

Vlad Zahorodnii requested to merge work/zzag/cherry-pick-quick-memory-leak into Plasma/5.23

A few plasma components cache QSGTexture. Those components rely on texture references going away with QSGNode users. However, with the current tear down logic, OffscreenQuickView won't destroy any paint nodes.

Destroy QQuickRenderControl before QQuickWindow to ensure that are no paint nodes left alive after OffscreenQuickView.
