This restores fast navigations to fully static PPR routes in Cache Components, even when prefetch hasn’t completed or prefetch={false} is used. In legacy versions of PPR, the prefetchDataRoute entries would be populated with .prefetch.rsc values containing static RSC payloads. This regressed in cache components, and the only static RSC payloads were in the .segments directory. However, when Next.js triggers a regular RSC request (non-prefetch), either because the prefetch hadn't completed yet or prefetch={false} was configured, we'd route to the empty fallback and trigger a function invocation.

This restores old behavior of emitting a .rsc file for a fully static route. This information technically also exists in the .segments directory, but it's split into parts, and it's now routed to unless explicitly done so via the next-router-segment-prefetch header. In addition to emitting the route, this also ensures we set prefetchDataRoute to point to this. This is how the Vercel adapter knows the file to serve.

An e2e regression test now asserts that prefetch={false} navigation does not wait for a dynamic render. The deploy test will be unblocked once vercel/vercel#14770 lands.
