IMPALA-12401: Support more info types for HS2 GetInfo() API

This patch adds support for 40+ additional TGetInfoType values in the
HiveServer2 GetInfo() API, improving ODBC/JDBC driver compatibility.

Previously, only 3 info types were supported (CLI_SERVER_NAME,
CLI_DBMS_NAME, CLI_DBMS_VER).

The implementation follows the ODBC CLI specification and matches the
behavior of Hive's GetInfo implementation where applicable.

Testing:
- Added unit tests in test_hs2.py for new info types
- Tests verify correct return values and data types for each info type
