Replace `turbopack://[project]/...` sourcemap uris with `file://...` in development (#71489)
This makes working with devtools more straightforward, reduces our own
overhead when tracing stack frames in the error overlay, etc.
Generated code from Turbopack or Next.js still use
`turbopack://[turbopack]` or `turbopack://[next]` respectively.
Test Plan:
- [x] Update tests
- [x] CI
