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 cb19621dfe Implementation of JS reload without crashing
Summary:
On JS reload the FabricUIManager and EventDispatcher didn't get release due to a retain cycle. This breaks the cycle.

In addition, force release the Scheduler on reload so that the stale classes get cleaned up properly, avoiding crashes. Also the surface now remounts the content correctly

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 beb3fcda34 Fabric: The first version of event dispatching pipeline
Summary:
This is the first attempt to implement some base part of event dispatching pipeline from end-to-end.
Even when it is working, all this is still incomplete and generally up in the air. We are still messing proper implementation of event queue, priority, and synchronization of react reconciliation process with event scheduling.

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.)
