Subject: [PATCH] feat: Add support for AWSTraceHeader message system attribute
in SQS
This change enhances the SQS mock to support the `AWSTraceHeader`
message system attribute.
Modifications include:
- Ensuring `Message` objects in `moto/sqs/models.py` correctly store
system attributes.
- Updating `SQSBackend.send_message` to pass through system attributes.
- Modifying `SQSResponse.receive_message` in `moto/sqs/responses.py`
to include `AWSTraceHeader` in the response when it's present on
the message and requested by you.
- Adding a new test case in `tests/test_sqs/test_sqs.py` to verify
the functionality of sending and receiving messages with the
`AWSTraceHeader` system attribute, covering scenarios where the
header is present, absent, requested, or not requested.
