Add Fibers to ReactDOMComponentTree

This adds precaching to ReactDOMFiber. I.e. adding a handle from the DOM
node to the internal Fiber. This means that we need to expose an internal
handle to the reconciler.

We use duck typing to figure out if it is a Fiber or Stack instance.

The new failing tests are failing because this is now able to actually
fire events onto Fibers and then the result of those events are
incorrect where as they were ignored before.
