libcamera: camera: Ensure deletion via deleteLater()
Object::deleteLater() ensures that the deletion of the Object takes place in a thread it is bound to. Deleting the Object in a different thread is a violation according to the libcamera threading model. On hot-unplug of a currently streaming camera, the last reference of Camera when dropped from the application thread (for e.g. QCam's thread), the destructor is then called from this thread. This is not allowed by the libcamera threading model. Camera is meant to be deleted in the thread it is bound to - in this case the CameraManager's thread.
