New Feature Idea: Allow raising `AbortHandlingException` to abort current handler & skip any remaining handlers for this event, mark it as completed immediately

[pirate]

class IgnoreEventException(Exception):
    pass


def some_handler(event: BaseEvent[Any]):
    raise IgnoreEventException()


event_bus.on('SomeEventToIgnore', some_handler)


If a handler raises `IgnoreEventException` it should be able to stop the execution of the other handlers after it when `parallel_handlers=False`.
