[rabbitmq] [rabbitmq] Add message_bytes_ram metric collection

[mahipdeora25]

Generated by FBO — DRAFT for human review

Closes FRAGENT-1309

Reality-check reasoning

The QUEUE_ATTRIBUTES list in rabbitmq/datadog_checks/rabbitmq/const.py defines all queue-level metrics collected via the Management API. It includes ('message_bytes', 'message_bytes', float) but there is no entry for message_bytes_ram. The metadata.csv also does not contain a rabbitmq.queue.message_bytes_ram metric entry. To implement this FR, ('message_bytes_ram', 'message_bytes_ram', float) would need to be added to QUEUE_ATTRIBUTES in const.py and a corresponding row added to metadata.csv.

Learned from exemplar PRs: #20174, #19401, #19536, #20697, #23457

This PR was opened as a Draft. A human should review the diff,
re-run validators if needed, and mark Ready for Review.
