refactor shared logic for turbopack-cli (#48307)
### What?
* move some shared runtime logic to turbopack
* use relative imports from internal code when possible
* move react-refresh logic to turbopack
* move benchmark code logic to turobpack
see https://github.com/vercel/turbo/pull/4553
### Why?
We want to have benchmarking again for turbopack PRs
We want to have a standalone turbopack cli (eventually)
We want to avoid duplicating the runtime code
### How?
refactoring, moving code
