KAFKA-14412: Decouple RocksDB access from CF (apache#15105)

To support future use-cases that use different strategies for accessing RocksDB, we need to de-couple the RocksDB access strategy from the Column Family access strategy. To do this, we now have two separate accessors: * `DBAccessor`: dictates how we access RocksDB. Currently only one strategy is supported: `DirectDBAccessor`, which access RocksDB directly, via the `RocksDB` class for all operations. In the future, a `BatchedDBAccessor` will be added, which enables transactions via `WriteBatch`. * `ColumnFamilyAccessor`: maps StateStore operations to operations on one or more column families. This is a rename of the old `RocksDBDBAccessor`. Reviewers: Lucas Brutschy <[email protected]>
