chore: update dependencies and implement multi-threaded TPCC support

- Updated `librocksdb-sys` to version 0.17.1 and `rocksdb` to version 0.23.0 in `Cargo.toml` and `Cargo.lock`.
- Refactored `RocksStorage` to use `TransactionDB` instead of `OptimisticTransactionDB`.
- Enhanced TPCC implementation to support multi-threading, allowing concurrent transaction execution with shared statistics collection.
- Added detailed comments on the threading strategy and architecture for clarity.
