Use faster hash algorithm (xxh128) on PHP 8.1+
Twig uses the `hash` function at runtime to convert template paths class names, each time a template is loaded. In a large project with a high granularity of templates (hundreds of `include` per page), this can become the most time consuming function as reported by Blackfire:

To optimise this use-case, [PHP 8.1 supports the xxHash hash algorithms](https://php.watch/versions/8.1/xxHash). `xxh128` is 60x faster that `sha256` according to the [benchmarks](https://php.watch/articles/php-hash-benchmark), and guarantee a very [low risk of collision](http://cyan4973.github.io/xxHash/).
I'm not able to test with PHP 8.1 for now. Before going further I would like to validate performance impact on a large list of file names.

Twig is a template language for PHP.
Twig uses a syntax similar to the Django and Jinja template languages which
inspired the Twig runtime environment.
