`xxh128` is 60 times faster than `sha256` (source: https://php.watch/versions/8.1/xxHash) but it's not cryptographically secure.

In previous versions we already used `xxh128` in some places. In this PR I propose to use it in all places where we don't need a cryptographically secure hash.

Comments:

* ~I also remove some `base64` encoding of binary hashes, etc. It looks convoluted and to me it looks unnecessary. But I can revert these changes if needed.~ **REVERTED**
* There are some places where we can probably use `xxh128` but I'm not sure, so I didn't. These:
  * https://github.com/symfony/symfony/blob/7.1/src/Symfony/Component/HttpKernel/EventListener/CacheAttributeListener.php#L71
  * https://github.com/symfony/symfony/blob/7.1/src/Symfony/Component/HttpKernel/HttpCache/Store.php#L421-L434
  * https://github.com/symfony/symfony/blob/7.1/src/Symfony/Component/HttpKernel/HttpCache/Store.php#L421-L434
* And there's this use case, where a function explicitly tells that we're generating a sha256 hash, so I'm not sure if changing it is a BC break: https://github.com/symfony/symfony/blob/7.1/src/Symfony/Component/Form/ChoiceList/Factory/CachingFactoryDecorator.php#L42-L65
