[DevTools] Expose "view source" options to Fusebox integration (#28973)

## Summary

Exposes the APIs needed by React Native DevTools (Fusebox) to implement
the "view element source" and "view attribute source" features.

## How did you test this change?

1. `yarn build` in `react-devtools-fusebox`
2. Copy artifacts to rn-chrome-devtools-frontend
3. Write some additional glue code to implement
`viewElementSourceFunction` in our CDT fork.
4. Test the feature manually.
