Use explicit pass for restoring controlled state instead of asap (#8176)

* Use explicit pass for restoring controlled state instead of asap

This gets rid of the first class ReactUpdates.asap scheduling. Instead of
scheduling a first class function to invoke later, I introduce an explicit
phase for restoring controlled state after dispatching events.

We assume that the deepest event target is the thing that needs its state
restored.

* Drop special cases for onChange in wrappers

We're now not using anything special about onChange handling in the
wrappers. Yay!
