Disallow server start with sync_replication_slots = on and wal_level < logical.
Replication slot synchronization (sync_replication_slots = on)
requires wal_level to be logical. This commit prevents the server
from starting if sync_replication_slots is enabled but wal_level
is set to minimal or replica.
Failing early during startup helps users catch invalid configurations
immediately, which is important because changing wal_level requires
a server restart.
