Add a publish-and-take test for rmw_take_sequence

[xiao-yang25]

Summary

• Expand the rmw_take_sequence test to publish and receive multiple messages.
• Use BasicTypes sequence storage matching the subscription type instead of the previous Strings storage.
• Publish three ordered messages and use a bounded wait-and-take loop to receive them.
• Verify the number of messages taken, the message and metadata sequence sizes, and message ordering.
• Retain the existing empty-subscription coverage.
• Add scoped cleanup for the publisher, wait set, messages, and information sequences.
