Docs: Implement Controls block

[tmeasday]

Telescoping on #20664

Issue: N/A

What I did

• Very similar to Docs: Created ArgTypes component and stories #20664, implemented a controls block. There is some small duplication with the deprecated ArgTable component, but it is very simple.

• Use it in DocsPage

How to test

• See stories
• Run an Autodocs page in a sandbox.

Checklist

• Make sure your changes are tested (stories and/or unit, integration, or end-to-end tests)
• Make sure to add/update documentation regarding your changes
• If you are deprecating/removing a feature, make sure to update

code/ui/blocks/src/argsHelpers.ts is an empty file?

Looks very clean!
