Fix some compiler warnings

- Remove deprecated Qt::AA_EnableHighDpiScaling and Qt::AA_UseHighDpiPixmaps
  from examples. High-DPI scaling is always enabled.
- Reorder initialization of members of QWebEngineDownloadRequestPrivate.
  Also remove m_ prefix from public members' name.
- Remove unused parameters from methods of DummyDelegate.
- Add missing overrides in auto tests.

Pick-to: 6.2
