pg_controldata: Show logical decoding status.

Browse Source 
The logical decoding status is stored in checkpoint records and used
to restore the status at server startup, but pg_controldata did not
show it. This information is useful for diagnosing issues around the
dynamic activation and deactivation of logical decoding.
