Add GUC option to control maximum active replication origins. This commit introduces a new GUC option max_active_replication_origins to control the maximum number of active replication origins. Previously, this was controlled by 'max_replication_slots'. Having a separate GUC option provides better flexibility for setting up subscribers, as they may not require replication slots (for cascading replication) but always require replication origins.
