libcamera: camera_manager: Bind CameraManager to threads

The CameraManager class uses the event dispatcher of the current thread.
This makes the CameraManager::eventDispatcher() and
CameraManager::setEventDispatcher() methods inconsistent, as they access
different event dispatcher instances depending on the calling thread.

Fix this by inheriting from the Object class, which binds the
CameraManager to a thread, and use the event dispatcher of the bound
thread.
