Fixed issue for PreparedStatement INSERT multiple values update count issue with triggers
This pull request refactors how update counts are determined for INSERT statements in the JDBC driver, ensuring more accurate update counts, especially for PreparedStatement executions involving triggers and multiple value inserts. It removes the subclass override mechanism for TDS token processing and centralizes the logic. Additionally, a new unit test is added to validate correct behavior with triggers and multiple inserts.

Refactoring and logic simplification:

• Removed the hasUpdateCountTDSTokenForInsertCmd() method and its overrides from both SQLServerStatement and SQLServerPreparedStatement, consolidating the logic for handling update counts for INSERT commands. [1] [2]
• Updated the condition in the TDS_DONE token processing to directly check for INSERT commands and execution method, rather than relying on the now-removed method.

Testing improvements:

• Added a new test, testPreparedStatementInsertMultipleValuesWithTrigger, to ensure that PreparedStatement correctly returns the number of inserted rows when using multiple values and triggers, addressing a prior bug where the update count could be incorrect.
