Add `IntlListFormatter`

See https://ungureanu.blog/2025/06/24/new-in-php-intl-8-5-intllistformatter-display-arrays-as-locale-aware-lists/

I'd suggest handling only a few locales (or maybe only "en" as a start), with the rules from https://github.com/unicode-org/cldr-json/blob/main/cldr-json/cldr-misc-full/main/en/listPatterns.json

I suggest implementing IntlListFormatter only for en, like all our other formatters in symfony/polyfill-intl-icu. Projects wanting to support all locales will need to install ext-intl to have access to the ICU data.

@stof this makes sense, it'll be a lot of work to keep them in sync with ICU data.

I'd like to work on in this weekend, but if someone's already working on it or would like to, please go ahead :)

@Ayesh are you still interested to work on this one? If not, I could pick it up too.

Oh cool, I started this morning, I will have the PR shortly. Looking forward to your review @BogdanUngureanu.
