Migration from package:intl to package:intl4x

[mosuem]

The intl package is widely used for i18n of Dart apps, but is hard to maintain and offers limited functionality. Instead of dedicating a lot of work to merge the recurring changes to CLDR data, improve code quality, slowly add features, and fix bugs, we decided to go a more future-proof route and replace it with package:intl4x.

This is a wrapper around the well maintained Unicode icu4x project and the browsers Intl object, thus providing bug-free(*) and feature-rich experiences on all platforms.

We will continue to support package:intl for at least as long as package:intl4x is still in experimental. Please help us in shipping this by letting us know your use cases and thoughts!
