libcamera: object: Document danger of deleting object from other thread
Object instances receive messages dispatched from the event loop of the
thread they belong to. Deleting an object from a different thread is
thus dangerous, unless the caller ensures that no message delivery is in
progress. Document this in the Object class documentation.
