D23070: Remove usage of QWeakPointer for QObject for thumbnails

[Frederik Gladhorn]

  Using a QWeakPointer for QObjects works, but has been deprecated for around seven years. QPointer does the same cleanly (track life-time of QObjects). If you use .toStrongRef() on a QWeakPointer to a QObject without going through QSharedPointer you are in UB land.
  In other words: this API is bad and will most likely be removed from Qt in the future.
