Add IT for session and jdbc query

[JackieTien97]

This pull request introduces support for handling the OBJECT data type as a binary blob in both JDBC and session APIs, and adds integration tests to verify correct behavior. The main changes include updating how OBJECT columns are processed and retrieved, and providing comprehensive test coverage for object and blob queries.

JDBC and Session API Enhancements

• Updated getBlob(int columnIndex) and getBlob(String columnLabel) in ClusterTestResultSet.java to support retrieving blob values from all underlying result sets and comparing them, instead of throwing UnsupportedOperationException. [1] [2]
• Modified IoTDBJDBCResultSet.java so that both BLOB and OBJECT data types are returned as byte arrays, ensuring consistent binary handling for object columns.

Query Engine and Transformer Adjustments

• Changed ColumnTransformerBuilder.java to treat the READ_OBJECT function as returning a BLOB type instead of OBJECT, aligning internal type handling for object columns with binary semantics. [1] [2]
• Removed unused import for ObjectType.OBJECT in ColumnTransformerBuilder.java.

Integration Test Coverage

• Added a new test class IoTDBObjectQueryIT.java to verify object and blob query behaviors via both JDBC and session APIs, including assertions for binary content, string representations, and correct query results.
