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

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:
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.

* The props parsing/conversion process was de-virtualized: we don't use virtual `apply` method to parse props anymore. Instead, we use old-fashioned constructors.
* All fields of Props classes which represent props values were marked as `const` which make impossible to modify them after the objects were created (even if we have non-const value-of/pointer-to the whole Props object). Those fields are also `public` now.
* All custom handwritten getters were removed (because we don't need them anymore).
So, now we don't need all those custom getters which makes code much more compact, performant and codegen-friendly.

Summary:
The previous approach simply didn't work. :(
As you might notice, in previous implementation of ViewShadowNode::cloneAndReplaceChild we used `ViewShadowNode` class for cloning `childNode`, and this is incorrect becasue `childNode` might be instance of any class.

Summary:
The new interface of ComponentDescriptor makes ShadowNode creation/cloning process a bit more explicit:
Now customers (UIManager) must prepare Props object explicitly before creation or cloning.
Besides general clarity, we need this to prepare for a new virtual `ShadowNode::clone()` method which will serve "virtual constructor" role,
redirecting execution to concrete ComponentDescriptor instance.
Actually, the whole purpose of concrete ComponentDescriptor instance is serve "virtual constructor" role (and all this code should be "templated").

Summary:
Motivation:
* We never should call `markDirtyAndPropogate()` during tree construction/mutation because it might affect trees in different thread/dimentions;
* In Fabric we basically always have to dirty nodes ourselves manually duting tree construction;
* In Fabric we don't have "scoped/limited" tree mutations which require recursive dirtying; any mutation is creation of the new tree instance;
* Default value of the `isDirty` flag is "false", so we have to change this right after creation of Yoga node (and after cloning).

Summary:
The modern Concurent Yoga's concept is:
We have to set parent/owner reference as part of `appendChild` process only if the current reference to parent/owner is `null`.
The motivation:
* Null-parent indicates that this node was not attached to anything yet;
* So, in this case there is no any concurrent memory access because we always create and (first time) attach the node on same thread;
* Simmetrical parent-child relationship indicates that we don't need to (re)clone assosiated ShadowNode (nor Yoga node).
