Code Review
This pull request introduces Intl.Locale to parse browser languages, which is a significant improvement over the previous manual string splitting. The new DomLocale extension type correctly handles complex language tags including script codes. The accompanying tests are thorough and validate the new functionality.
My review focuses on the new DomLocale and DomLocaleOptions extension types in dom.dart. I've suggested adding documentation as required by the style guide, aligning the constructor naming with existing conventions in the file, and removing a property that doesn't seem to belong to the underlying JS API. The rest of the changes look good.
