Only show QWindows after QScreen destruction if coming from virtual sibling
For windows that were shown on an external screen (not a virtual sibling of the primary screen), eg. on iOS, it doesn't make sense to re-show the window when moved back to the primary screen. By moving the logic into the QScreen destructor, we ensure that the code path is hit both for the old and unsupported style way of destroying QPlatformScreen by deleting it directly, and the new and safe way of using QPlatformIntegration::destroyScreen(), while still allowing clients to manage the windows themselves by emitting screenRemoved() before applying our fallback logic. [ChangeLog][QtGui][Important Behavior Changes] QWindows will no longer be re-shown automatically when moved from a destroyed QScreen, unless that QScreen was a virtual sibling of the primary screen.
