Tim NeutkensandGitHub c23d1a946c feat(turbopack): support import.meta.env (#96225) ...

## Summary

- add native Turbopack support for `import.meta.env.DEV`, `PROD`,
`MODE`, `BASE_URL`, and `SSR`
- statically analyze built-in values for dead-code elimination while
exposing the complete runtime object
- derive `BASE_URL` from the Next.js `basePath` and include
Vite-compatible trailing-slash formatting
- add TypeScript declarations, focused execution and Next.js integration
coverage, and Vite migration documentation

## Verification

- `cargo fmt --all -- --check`
- `cargo nextest run -p turbopack-tests -E 'test(import_meta_env)'`
- `pnpm build-all`
- `pnpm --filter=next types`
- `NEXT_TEST_PREFER_OFFLINE=1 pnpm test-dev-turbo
test/e2e/import-meta-env/import-meta-env.test.ts`
- `NEXT_TEST_PREFER_OFFLINE=1 pnpm test-start-turbo
test/e2e/import-meta-env/import-meta-env.test.ts`
