Fix tree-shaking of Circuit UI

[connor-baer]

Purpose

While upgrading the Next.js template to Circuit UI v7, I discovered that Circuit UI can no longer be tree-shaken because Vite combines all code into a single file. I had assumed that bundlers were smart enough to tree-shake the code regardless.

Approach and changes

• Use the vite-plugin-no-bundle to configure Vite to retain the original file structure

Definition of done

• Development completed
• Reviewers assigned
• Unit and integration tests
• Meets minimum browser support
• Meets accessibility requirements
