Test Vite version of React Server Components with Hydrogen

[jplhomer]

Blocked by Shopify/hydrogen#40
Part of Shopify/hydrogen#35

Once we have react-server-dom-vite in the React repo, we should swap out our reverse-engineered implementation with the real version.

There are two caveats with this:

• SSR won't work (yet)
• There might be critical bugs

I'm particularly interested in the latter part, because we'll need to fix these bugs and blockers before RSC goes live. This is an opportunity to contribute fixes upstream in React and to the third-party packages we use.

For example: we might notice that React Router stops working. Or the way we're using Context in Hydrogen doesn't work in RSC.
