[node-webstreams] Use React builds for Node.js (#81048)
Closes https://linear.app/vercel/issue/NEXT-4560/
React now exposes Web stream APIs in their Node.js builds so we can use the Node.js builds.
That enable us to use some of the Node.js goodies like `async_hooks` which is required for the React's experimental Server Requests track.
## Test plan
`next-server` runtimes did not increase bundle size. We even saved some in the `app-page` entries since we no longer have to bundle Edge and Node.js versions of React Server. We can rely solely on the Node.js variant of React Server.
A build of `test/e2e/app-dir/hello-world` shows no significant bundle size changes
