 Emoji: Update the Twemoji loader to include the rainbow flag.

 [38179] added support for the rainbow flag to core, but platform
 compatibility is a bit strange, because the flag was defined out of sync
 with the usual Unicode release cycle. For example Android N supports all
 Unicode 9.0 emoji, but doesn't support the rainbow flag thus the rainbow
 flag isn't rendered.
 The Twemoji loader already has an exception for flags - it'll load if the
 browser supports everything but flags, and then only replace flag emoji,
 leaving everything else as native rendering. To provide a seamless
 experience for all flags the loader now uses the rainbow flag to test flag
 support.

 Props pento.
 See #37543.
 Fixes #37566.
