Add data attributes on @next/font usage (#45296)
Adds `data-next-font` data attribute to the preload tag if added by
`@next/font`.
```js
// Using `size-adjust` fallback font.
<link data-next-font="size-adjust" rel="preload" href="..." as="font" type="font/woff2" crossorigin="anonymous">

// Not using `size-adjust` fallback font.
<link data-next-font="" rel="preload" href="..." as="font" type="font/woff2" crossorigin="anonymous">
```

If no fonts are preloaded, the tag is added on the preconnect tag.

Fixes NEXT-350
