Towards https://github.com/flutter/flutter/issues/164315. See also: https://github.com/flutter/flutter/blob/master/docs/tool/Engine-artifacts.md. There are more usages in `flutter/flutter`, but some will require more specialized review (i.e. from release folks, or the Dart SDK team), so I'll split those off. ~~Requires https://github.com/flutter/flutter/pull/164317 to merge first.~~ ✅
