[FLINK-6032] [cep] Clean-up operator state when not needed.
The CEP operator now cleans the registered state for a key. This happens:
1) for the priority queue, when the queue is empty.
2) for the NFA, when its shared buffer is empty.
3) the key is removed from the `InternalWatermarkCallbackService` when both
of the above are empty.
