hey @Chaoba thanks for starting looking into it. a quick note here: the gist of the ticket is to move all map events to mapbox-gl-native while maintaining backwards compatibility. so essentially we need to cut two PRs: one that removes all maps events from events repo and another one that adds them to maps sdk. Please consult with @tobrun or @LukasPaczos about what is the right place for these events

[Chaoba]

@andrlee We should also create a PR for auto, right?

@Chaoba LGTM! Let's merge and test mapbox/mapbox-gl-native#14309 with snapshot.
