  Thanks for submitting a pull request!
We appreciate you spending the time to work on these changes. Please
provide enough information so that others can review your pull request.
The three fields below are mandatory.

Before submitting a pull request, please make sure the following is
done:

1. Fork [the repository](https://github.com/facebook/react) and create
your branch from `main`.
  2. Run `yarn` in the repository root.
3. If you've fixed a bug or added code that should be tested, add tests!
4. Ensure the test suite passes (`yarn test`). Tip: `yarn test --watch
TestName` is helpful in development.
5. Run `yarn test --prod` to test in the production environment. It
supports the same options as `yarn test`.
6. If you need a debugger, run `yarn test --debug --watch TestName`,
open `chrome://inspect`, and press "Inspect".
7. Format your code with
[prettier](https://github.com/prettier/prettier) (`yarn prettier`).
8. Make sure your code lints (`yarn lint`). Tip: `yarn linc` to only
check changed files.
  9. Run the [Flow](https://flowtype.org/) type checks (`yarn flow`).

## Summary

This PR updates the Rollup build pipeline to generate sourcemaps for
production build artifacts like `react-dom.production.min.js`.

It requires the Rollup v3 changes that were just merged in #26442 .

Sourcemaps are currently _only_ generated for build artifacts that are
_truly_ "production" - no sourcemaps will be generated for development,
profiling, UMD, or `shouldStayReadable` artifacts.

The generated sourcemaps contain the bundled source contents right
before that chunk was minified by Closure, and _not_ the original source
files like `react-reconciler/src/*`. This better reflects the actual
code that is running as part of the bundle, with all the feature flags
and transformations that were applied to the source files to generate
that bundle. The sourcemaps _do_ still show comments and original
function names, thus improving debuggability for production usage.

Fixes #20186 .

<!--
Explain the **motivation** for making this change. What existing problem
does the pull request solve?
-->

This allows React users to actually debug a readable version of the
React bundle in production scenarios. It also allows other tools like
[Replay](https://replay.io) to do a better job inspecting the React
source when stepping through.

## How did you test this change?

- Generated numerous sourcemaps with various combinations of the React
bundle selections
- Viewed those sourcemaps in
https://evanw.github.io/source-map-visualization/ and confirmed via the
visualization that the generated mappings appear to be correct

I've attached a set of production files + their sourcemaps here:

[react-sourcemap-examples.zip](https://github.com/facebook/react/files/11023466/react-sourcemap-examples.zip)

You can drag JS+sourcemap file pairs into
https://evanw.github.io/source-map-visualization/ for viewing.
