React Router 7 integration

[phryneas]

From my side, this works now and I could even circumvent the need for a PR to turbo-stream (although it would be nice if that would have native support for ReadableStream).

There is one outstanding type PR for remix-run/react-router#12264, but I think we can already get this reviewed at this point.
