Add support for MessageGroupId in standard queues

[areinel]

AWS now supports MessageGroupId on standard queues to enable fair queues, which mitigate the “noisy neighbor” impact in multi-tenant queues and help maintain consistent message dwell times across tenants
(https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-fair-queues.html).

This change ensures:

FIFO queues always get MessageGroupId (defaulting to default) and MessageDeduplicationId.
Standard queues can pass MessageGroupId without triggering FIFO-only logic.

The new functionality to support MessageGroupId in standard queues lacks test coverage. The existing test_predefined_queues_put_to_queue only verifies DelaySeconds behavior. Consider adding a test case that verifies MessageGroupId is correctly passed to send_message for standard queues when provided in message properties.
