Add dispatchEvent to fragment instances (facebook#32813)

`fragmentInstance.dispatchEvent(evt)` calls `element.dispatchEvent(evt)`
on the fragment's host parent. This mimics bubbling if the
`fragmentInstance` could receive an event itself.

If the parent is disconnected, there is a dev warning and no event is
dispatched.
