Date/Time: Rewrite and simplify `date_i18n()` using `wp_timezone()` to address multiple issues with certain date formats and timezones, while preserving some extra handling for legacy use cases.
Improve unit test coverage. Props Rarst, remcotolsma, raubvogel. Fixes #25768. Built from https://develop.svn.wordpress.org/trunk@45882 git-svn-id: http://core.svn.wordpress.org/trunk@45693 1a063a9b-81f0-0310-95a4-ce76da25c4cd
