Turbopack: Add `--debug-build-paths` support to filter routes (#88655) Add support for the `--debug-build-paths` flag in Turbopack builds. Previously this flag only affected which routes were prerendered (statically generated), but the bundler still compiled all routes. Now routes are filtered early in `Project::entrypoints()`, so excluded routes are never compiled by Turbopack. Framework routes like `/_not-found` and `/_error` are always included to ensure the runtime works correctly. This significantly reduces build times in large apps when building individual routes for debugging purposes. It also allows us to exclude building incompatible paths in end-to-end tests depending on whether `__NEXT_CACHE_COMPONENTS` is defined or not (see upstack PR).
