Sets the isolation level of the current transaction.
@param string $level The transaction isolation level to use for this transaction.
This can be either [[Transaction::READ_UNCOMMITTED]] or [[Transaction::SERIALIZABLE]].
@throws NotSupportedException when unsupported isolation levels are used.
SQLite only supports SERIALIZABLE and READ UNCOMMITTED.
