Allows compatible clients to preload mandatory assets like scripts, stylesheets or images according to [the "preload" working draft of the W3C](https://www.w3.org/TR/preload/).
Thanks to this PR, Symfony will automatically adds `Link` HTTP headers with a `preload` relation for mandatory assets. If an intermediate proxy supports HTTP/2 push, it will convert preload headers. For instance [Cloudflare supports this feature](https://blog.cloudflare.com/using-http-2-server-push-with-php/).
It dramatically increases pages speed and make the web greener because only one TCP connection is used to fetch all mandatory assets (decrease servers and devices loads, improve battery lives).
Usage:
Updated version:
```html
<html>
<body>
Hello
<script src="{{ preload(asset('/scripts/foo.js'), 'script') }}"></script>
</body>
</html>
```
~~First proposal:~~
```html
<html>
<body>
Hello
<script src="{{ preloaded_asset('/scripts/foo.js', 'script') }}"></script>
</body>
</html>
```
- [x] Add tests
