This PR ensures that CDC keeps working correctly in the recovery mode after leaving the raft-based topology. We update `system.cdc_local` in `topology_state_load` to ensure a node restarting in the recovery mode sees the last CDC generation created by the topology coordinator. Additionally, we extend the topology recovery test to verify that the CDC keeps working correctly during the whole recovery process. In particular, we test that after restarting nodes in the recovery mode, they correctly use the active CDC generation created by the topology coordinator.
