Add next/font import (#45891) Enables using `next/font` by adding `@next/font` as a dependency and reexporting its loaders. Always generates the `font-loader-manifest` as we can't know beforehand if the user intends to use `next/font` or not. Also adds telemetry for `next/font` usage. The tests are updated to use `next/font`. But `@next/font` is tested in `test/e2e/next-font/index.test.ts` and `test/e2e/app-dir/next-font` as well to ensure it doesn't break.

You have tried to use `next/font` with a custom babel config. When your application has a custom babel config you opt-out of the Next.js Compiler which is required to use `next/font`.
#### Possible Ways to Fix It
- Remove your custom babel config and use the Next.js Compiler
