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:
During transforming raw prop (`rawProps[<prop>]`) to typed props (`MyProps.<prop>`) we can face three different cases:
* `rawProps` collection has proper serialized value for the key. In this case, we have to set a new value of the typed prop converting value using `fromDynamic`.
* `rawProps` collection does not have value for the key. In this case, we have to copy a value from source prop (`sourceValue`).
* `rawProps` collection has `null` value for the key. This is the special case which means that the prop was removed from the particular component instance and we have to reset it to some *default* value (which is *not* the same as `sourceValue`). Now the default value of the `defaultValue` (sic!) argument is a default value of the type of the value (which may be different from logical default value).
We didn't handle the last case previously and this caused crashes (and unexpected behavior) because `fromDynamic` often cannot handle `null` value.
And yes, all this mean that we also have to update all `convertRawProp` call sites where logical default values are not equal to type-specific default values. This is a potential error-prone place, especially because now we have to specify logical default values in two places (in a prop declaration and in a parameterized constructor). And seems there is no way to avoid that without performance loss (because both of those places are basically constructors).
My hope is that codegen (where default values are also defined in JavaScript) will help with it eventually.

Summary:
The current implementation of React Native uses `Size` as the underlying type of `textShadowOffset` which is clearly terribly wrong (especially because negative size values makes no sense). This mistake was borrowed from `NSShadow`, I believe.
I don't have time to fix this in every implementation of RN now, so let's use `Size` in Fabric as well.

Summary:
`LayoutableShadowNode.cpp` includes `"LayoutableShadowNode.h"` as well as `<fabric/core/LayoutContext.h>`. In turn, `LayoutContext.h` then includes `<fabric/core/LayoutableShadowNode.h>`. `LayoutContext.h` doesn't actually require `LayoutableShadowNode.h`, but this unnecessary inclusion can cause duplicate definition errors if the two include paths don't map to exactly the same file. This patch removes the unnecessary include.
The CI's build system should cover the testing needed.
[INTERNAL] [MINOR] [fabric] - Remove an unnecessary include in fabric/core/layout.

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.

Summary:
It's maybe not so important/crucial, but this thing bothers me a lot.
We use raw opaque `EventTarget`, `InstanceHandle` and `EventHandler` pointers in application layer quite a lot and we don't have any kind of type-safety here. I believe all those opaque types should be represented as named scalar types which compiler at least can differentiate at compile time.
So I propose introducing named aliases for them which will point to particular empty `struct`s. This will allow us to tag types properly in all functions and methods and ensure that we pass right values as right arguments.
Again, they are *just aliases*, which are effectively still `void *`, no any additional logic or names are involved.
Unfortunately, those nice type names are already taken by `JSIFabricUIManager` local anonymous namespace (even if they are inside anonymous namespace we cannot use them https://stackoverflow.com/questions/3673353/anonymous-namespace-ambiguity). I think it's fair to rename them because... it's local. And we already use `Wrapper` suffix for them anyways.

Given that fact that life-time of YGNode and ShadowNode objects must be idential and that we always allocate ShadowNode on heap,
we can embed YGNode object right inside ShadowNode object and use pointer to it safely.

I recently realized (Thanks David!) that we should not use `shared_ptr` for storing YGNode*
because ShadowNode does not share ownership of the Yoga node with anybody.
So the lifecycle of shadow node and yoga node must be synchronized (this is already the case but changing to unique_ptr makes this explicit and a bit more performant).
