Once we switch to RocksDB, there will be 3 database dependencies - SQLite, Sled, RocksDB.
There is no special reason to use Sled - it was arbitrarily selected for ergonomics. So, we can migrate its code over to a different DB e.g. RocksDB and remove one unnecessary dependency. This is an internal operational change that does not have any material impact on the chain.
