Summary:
EventTargetWrapper and EventTarget were merged into one class that controls an `instanceHandle` reference and extracting a strong reference to it.
This diff also decouples the operation of retaining a strong reference (with checking a `enabled` flag) from actual usage of this reference. This allows to wrap into a mutex only first part of this process and avoid possible deadlocks.

Summary:
Now the event delive pipeline supports `JSI::Value`-based payload. Instead of passing `folly::dynamic`, now we are passing `std::function<jsi::Value(jsi::Runtime &runtime)>` as factory that can build a `JSI::Value` with given `jsi::Runtime` and any captured data.
The old (now legacy) way of calling `EventEmitter::dispatchEvent(..., const folly::dynamic &payload, ...)` is also supported.

Summary:
We double down on JSI in Fabric. So, practically, JSI is now a hard dependency for Fabric. I hope it's for good.
Now `jsi::Runtime` is coupled with scheduling via `EventExecuter`, so we have to make `jsi::Runtime` a part of `EventBeat` to proxy runtime reference to bindgings.

Summary: Apparently, the standard does not guarantee that the vector is empty after moving from it. So, let's clear it explicitly instead of asserting the emptiness.

Summary: Instead of relying on explicit `RawEventDispatchable` function, we simply check the existence of the `weak_ptr` to `EventTarget`. This is efficient and sufficient because only an EventEmitter retains an associated EventTarget.

Summary:
As we did in the previous diff, here we implemented `EventEmitter`'s ownership model as a `shared_ptr`. This change fixes problem with leaking `WeakObject`s which happens on hot-reload.
So, in short:
* `EventTargetWrapper` object owns `jsi::WeakObject` that can be converted to actual `jsi::Object` that represent event target in JavaScript realm;
* `EventTargetWrapper` and `jsi::WeakObject` objects must be deallocated as soon as native part does not need them anymore;
* `EventEmitter` objects retain `EventTarget` objects;
* `EventEmitter` can loose event target object in case if assosiated `ShadowNode` got unmounted (not deallocated); in this case `EventEmitter` is loosing possibility to dispatch event even if some mounting-layer code is still retaining it.

Summary:
@public
EventQueue is a queue of events that synchronizing event dispatching with given Event Beat.
The only difference between UnbatchedEventQueue and BatchedEventQueue is that UnbatchedEventQueue `induce` an Event Beat right after enqueing an event.
