Sort index.js by alphabetical order and add category comments. (#30217)

Summary:
As of right now, index.js contains a big blob of imports that are mostly in alphabetical order, with a few exceptions. In addition, the imports aren't separated by Components / API / Plugins, so comments were added for ease of future maintainability.

## Changelog

[Internal] [Changed] - Reordered imports into alphabetical order and added comments to divide imports into sections (components, apis, plugins, prop types)

Pull Request resolved: #30217

Test Plan:
This change did not change the codebase. Building rn-tester still works.
