feat: add **kwargs support to create_table_with_index_params for heap organization

- Add **kwargs parameter to create_table_with_index_params method
- Pass **kwargs to ObTable constructor to support mysql_organization='heap' and other parameters
- Set extend_existing=True as default in kwargs to maintain backward compatibility
