Replace turbopack://[project]/... sourcemap uris with file://...

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: CI. Update snapshots.
