The stream-based XML serialization API resides in corelib/serialization. Move the steambookmarks example there. The Qt XML documentation is updated to no longer refer to this example code directly and refer to the direct location in the example documentation instead. Task-number: QTBUG-110647 Pick-to: 6.5 Change-Id: Id36fb04a6acb7b8d1eb008f61568fe0abc221e3d Reviewed-by: Marc Mutz <marc.mutz@qt.io>
