Expose prerender() for SSG in stable

[sebmarkbage]

When we added renderToReadableStream we added the allReady helper to make it easier to do SSG rendering but it's kind of awkward to wire up that way. Since we're also discouraging renderToString in React 19 the cliff is kind of awkward. (As noted by Docusaurus.)

The idea of the react-dom/static prerender API was that this would be the replacement for SSG rendering. Awkwardly this entry point actually already exists in stable but it has only undefined exports.

Since then we've also added other useful heuristics into the prerender branch that makes this really the favored and easiest to use API for the prerender (SSG/ISR) use case.

prerender is also used for Partial Prerendering but that part is still experimental.

However, we can expose only the prerender API on react-dom/static without it returning the postponeState. Instead the stream is on prelude. The naming is a bit awkward if you don't consider resuming but it's the same thing.

It's really just renderToReadable stream with automatic allReady and better heuristics for prerendering.
