feat: add React Compiler support for Autocomplete

[joshblack]

Closes N/A

Follow up to #8105.

This PR updates Autocomplete so it can be removed from the React Compiler unsupported list. The main runtime change is in AutocompleteInput, where the callback dependency handling now avoids the hook suppression that caused React Compiler to skip the file.

As a result, Autocomplete can be compiled as part of the React Compiler migration while keeping the public API and behavior unchanged.

Changelog

Rollout strategy

• Patch release
• Minor release
• Major release; if selected, include a written rollout or migration plan
• None; if selected, include a brief description as to why

Selected minor since this enables React Compiler output for Autocomplete as part of the migration.

Testing & Reviewing

• npm run format:diff
• npm run lint
• npm run lint:css
• npm test -- --run
• npm run type-check
• npm run build

Would love a review on the AutocompleteInput dependency handling to confirm this stays equivalent to the previous callback behavior.
