Sebastian Markbage 5d9326be29 Remove instanceHandle, pass event target instead + add dispatchToEmptyTarget
Summary:
Removes the concept of instance handle. Instead we pass the event target
to createNode and don't pass it to subsequent clones.

The life time of the event target is managed by native (the event emitter).
It has to be released manually.

Kevin Gozali 20a8673b48 iOS: create EventTarget when creating EventEmitter and keep it until the emitter is deallocated.
Summary:
@public
There are some race conditions between VM objects getting deallocated and the instanceHandle held by the eventEmitter can point to deallocated memory space, causing undefined behavior like a crash.
For now, keep a strong ref to the eventTarget inside EventEmitter to avoid that scenario. This is a temporary workaround.

Kevin Gozali 2ca4770011 fabric: send events via JS thread
Summary: Calling the event emitters on the main thread seems to be problematic, so let's dispatch it via the JS thread. This requires some changes to make "eventTarget" single-use because otherwise the binding would need to synchronize the actual JS call with the act of releasing the target.

Valentin Shergin b3b72bbdcf Fabric: Using types `EventTarget`, `EventHandler` & co. instead of `void *` everywhere
Summary:
Nothing actually changed besides type names... which actually helps me found an issue in FabricUIManager!
Now there is no a single `void *` in Fabric/C++ and JavaScript bindings. Yay!

Valentin Shergin 2a3025da97 Fabric: Application layer of events infrastructure
Summary: This implements `EventHandlers` abstract class (aka "Events Guy") which encapsulates `eventDispatcher` and `instanceHandle` (and ownership of future `eventTarget`), all of this as part of existing {ShadowNode + Props + LayoutMetrics + LocalData + Descriptor + (and now) EventHandlers} infra. (We don't plan to add anything else to this model. Ever.)
