Changelog: [Internal]
Using `empty()` vs `size() == 0` or `size() > 0`.
It is a more semantic way to check whether container is empty or not.

Summary:
It's not fully clear why it happens but sometimes UIKit cancels (calling some UIGersureRecognizer interface) some UITouch events that seem never previously started. That might be a bug in UIKit or in our local registry.
That happens extremely rarely but happens.
After this change, RCTSurfaceTouchHandler will ignore those touches in production but crash in debug mode (I hope we can find a repro case and fix it).
Anyway, ignoring canceling of touches that RCTSurfaceTouchHandler is not aware of should not be a big deal.

Summary:
Surprisingly, `UITouch::view` property might be nil in some cases (the documentation does not specify in which ones), and that actually happens. That breaks the calculation of a touch position relative to a view on which the touch began. This diff implements storing the view inside ActiveTouch, so we always can access it when we need it. That's similar to how it's implemented in Paper's TouchHandler.

Summary: The previous rename from RCT->RN prefix ended up causing some confusions on which prefix to use for which files and under what circumstances. To avoid further confusion before we're done with the re-architecture project, let's keep them as RCT.

Summary:
Apparently, if a gesture recognizer got 'reset', OS does not call `touchesCancelled:` method, so we have to do it manually.
To implement this we have to split `_dispatchTouches:eventType:` into two methods: the first converts Objective-C touches to C++ touches, the second consumes that. We have to do this because during reset we don't have a collection of UIKit touches.

Summary: Every C++ engineer (except me several months ago) knows that `operator []` can mutate the collection (Yeah! Don't ask), so this is especially dangerous if your hash function is broken (see the previous diff).

Summary:
Without this fix the PointerHasher hashed not a pointer, but an address where the pointer is stored, which is obviously incorrect.
The incorrect hash function compromised the whole `_activeTouches` caused many issues with logically invalid invariants (e.g. removing element from the collection silently didn't work).

Summary:
This diff includes two changes:
1. Even though `RCTViewComponentView` conforms to `RCTTouchableComponentViewProtocol`, it never implemented this protocol. This diff makes the correction.
2. Make the necessary changes to `RCTSurfaceTouchHandler` required by the changes in `RCTTouchableComponentViewProtocol`. This means modifying the `ActiveTouch` struct to hold `SharedTouchEventEmitter`s. It also means passing in the touch point to the `componentView`'s `touchEventEmitterAtPoint` method.

Summary:
@public
After reading about move-semantic and rvalue refs I realized that we (I) definitely overuse `auto &&` (aka universal reference) construction. Even if this is harmless, does not look good and idiomatic.
Whenever I used that from a semantical point of view I always meant "I need an alias for this" which is actually "read-only reference" which is `const auto &`.
This is also fit good to our policy where "everything is const (immutable) by default".
Hence I change that to how it should be.

Summary:
Using `EventHandlers` name was a bad idea, and I cannot tolerate it anymore.
The worst part of it is that when you have a collection of `EventHandlers` objects you cannot use plural word to describe it because `EventHandlers` is an already plural word.
And, this object is actually an event emitter, the thing on which we call events.

Summary:
RCTSurfaceTouchHandler is a complete rewrite of RCTTouchHandler which uses direct Fabric-specific event dispatching pipeline and several new approaches to managing active events (such as high-performant C++ collections, better management of identifier pool, and so on).
Besides that, the new implementation is much more W3C compliant that it used to be (see old TODOs near `receiveTouches()` implementation in Javascript).
So, touch events work now!
