d70b854294 Turbopack: fix pages index normalization for --debug-build-paths (#94341)
Recreation of https://github.com/vercel/next.js/pull/90314

---

## Summary
- Fix `--debug-build-paths` pages normalization in Turbopack so
`pages/<name>/index.tsx` maps to `/<name>` (matching JS
`getPageFromPath()` behavior).
- Handle index page edge case: `/index.tsx -> /`.
- Keep regression coverage in
`test/production/debug-build-path/debug-build-paths.test.ts` with a
generic fixture `pages/with-index/index.tsx`.

## Current Behavior Reference
- CI run (before this fix) that failed as expected for this bug:
-
https://github.com/vercel/next.js/actions/runs/22266469801/job/64413677099?pr=90314#step:35:216

## Root Cause
Rust-side debug-build-path normalization removed file extensions but did
not remove `/index`, producing route keys like `/with-index/index` while
pages route keys are `/with-index`. That mismatch filtered out the page
and caused `PageNotFoundError` during page-data collection.
