Refactor AQL JSON Serialization and Update RocksDB Integration Tests

- Moved JSON serialization functions for AST nodes from `aql_parser.cpp` to a new file `aql_parser_json.cpp` to reduce compile-time pressure.
- Updated `test_lib_boost_integration.cpp` to use `boost::asio::post` for posting tasks to the IO context.
- Enhanced `test_lib_hnsw_integration.cpp` to compute distances using the public API of hnswlib, ensuring accuracy in distance calculations.
- Revised `test_lib_rocksdb_integration.cpp` to reflect the new TransactionDB-based API, including updates to transaction handling, batch operations, and multi-get functionality.
- Added a PowerShell script to automate the addition of `open()` calls after `RocksDBWrapper` construction in benchmark tests.
