IGNITE-21167 Sql. Jdbc. Raise a clearer error message when the tx control statement is used in non-autocommit mode

[xtern]

https://issues.apache.org/jira/browse/IGNITE-21167

In jdbc handler exception message has changed from Transaction control statement cannot be executed within an external transaction to more understandable Transaction control statements are not supported when autocommit mode is disabled

JdbcHandlerBase abstract class was introduced to handle such errors uniformly.
