Summary: It appears that `(e: BubblingEvent<T>) = mixed` exists only in given context and it's pointless to keep in this way. It could be simplified to `BubblingEventHandler<T>` without any negative consequences and that's the motivation of this diff. The only tradeoff of this decision is leaving an opportunity to declare Bubbling/Direct event in the top of the file bc then analysing the code becomes much more difficult. However, it's not used anywhere so it's not a problem now and probably any time. Also, changes the names to `DirectEventHandler` and `BubblingEventHandler` which are more related to current state. The names were updated in many places in code. Reviewed By: rubennorte Differential Revision: D16054571 fbshipit-source-id: 741d075eb46b80bac8eb73a6b30fc0b448cb3902
