Add full CREATE EVENT NOTIFICATION parsing support (#39)

Parse complete CREATE EVENT NOTIFICATION syntax including:
- ON SERVER/DATABASE/QUEUE scope with queue name support
- WITH FAN_IN option
- Event type and event group lists with PascalCase conversion
- TO SERVICE with broker service and instance specifier

Enable Baselines100_EventNotificationStatementTests100 and
EventNotificationStatementTests100 tests.
