…r#12478)

Ports flutter/flutter#190206 to `material_ui` following flutter/flutter#188444.

Fixes flutter/flutter#190205.

This change prevents an older asynchronous `SearchAnchor.suggestionsBuilder` request from replacing the results of a newer request.

It assigns an incrementing ID to each suggestions request and only applies the result when it still represents the latest request.

**Note**: The Flutter team is currently trialing the use of [Gemini Code Assist for GitHub](https://developers.google.com/gemini-code-assist/docs/review-github-code). Comments from the `gemini-code-assist` bot should not be taken as authoritative feedback from the Flutter team. If you find its comments useful you can update your code accordingly, but if you are unsure or disagree with the feedback, please feel free to wait for a Flutter team member's review for guidance on which automated comments should be addressed.
