refactor: Update rocksdb (#5568)

This change updates RocksDB to its latest version. RocksDB is backward-compatible, so even though this is a major version bump, databases created with previous versions will continue to function.

The external RocksDB folder is removed, as the latest version available via Conan Center no longer needs custom patches.
