Summary: This diff implements the HorizontalScrollView component for Android Fabric C++, as part of this diff I also re-named the components AndroidHorizontalScrollContentView for RCTAndroidHorizontalScrollContentView and AndroidHorizontalScrollView for RCTAndroidHorizontalScrollView. This might sound against our plan of removing the RCT preffix, but it is to make it simpler to map components between current implementation of RN and Fabric (otherwise we don't know when to add the RCT preffix in Android side to find the right View Manager), later we can just remove the preffix from C++, Android, iOS and JS.

ShadowNode class is designed to share `props` and `children` objects between instances. Given that all *Props classes are immutable, it's very easy to share them and we do this from the day one. The `children_` collection is more tricky though because ShadowNode class has a couple of mutation methods. Previously, we dealt with it very simply by copying the whole vector in constructors, and that was far from optimal. Now we store a special flag that indicates that the children list is shared among nodes, and we clone this before the first mutation.
Sharing a `shared_ptr` should be much more efficient (cost of atomic refcount increment) than instantiating whole new collection (an allocation).

Previously, all ConcreteShadowNode subclasses had to override `getComponentName()` function to specialize a name of the component. And often it was all that those subclasses do. Now, it's a template argument; and many ShadowNode classes can be created as oneliners via *just* specializing ConcreteShadowNode template.
Unfortunately, C++ does not allow to use `std::string`s or string literals as template arguments, but it allows to use pointers. Moreover, those pointers must point to some linked data, hence, those values must be declared in .cpp (not .h) files. For simplicity, we put those constants in Props classes, (but this is not a strong requirement).

This diff consists of many interdependent changes which support one simple idea: YogaLayoutableShadowNode is now using YGNode children to iterate on them (it previously relied on `ShadowNode::getChildren()`). All other changes are just an unavoidable consequence of that. Hence we don't need to filter child nodes every single time when we do layout anymore! The logic around `clone callback` is also drastically simpler now.
The new approach also implies that `LayoutableShadowNode` and `YogaLayoutableShadowNode` don't use `shared_ptr`s to refer to ShadowNode objects because new relationship does not imply ownership. No more `SharedShadowNode` objects in those two classes.

Non-null owner pointer in Yoga node indicates that this node is already being used by some other subtree, so it must be cloned in case of possible (re)layout.
Theoretically, this node must/can be cloned by Yoga right before applying a new layout to this node, but Yoga has a special optimization that uses that fact that Yoga always cloning *all* children of a particular node altogether. This is not true for React; to meet React and Yoga worlds we double check the owner pointer in `addChild` and clone node preliminary if needed.

... and it's as efficient as it was before.
The previous version of the algorithm used `sourceNode` reference to know the previous state of the node to call the algorithm recursively.
That wasn't so good because of several reasons:
- It was fragile because we had two different sources of the truth of the "previous state of the tree": committed tree and source node pointer;
- We had to store weak pointers to source nodes inside cloned nodes. That is not free in terms of performance;
- The old approach introduced a constraint that all previously used and now reinserted nodes must be cloned to update source node (otherwise, the algorithm would regenerate instructions recreating already existing subtrees);
- That cloning required access to `isSealed` flag which is supposed to be a debug-only thing (that actually affects performance and must be compile-out for release builds).
The new approach compares nodes with same react tag and naturally cloning-artifacts resilient.
Yes, the new approach uses a map of inserted nodes, but the previous one already had it (otherwise there is no way to tell which nodes should be "deleted"). And anyway, this is a very little map that exists for a very little period of time.

This is follow up for D8601600 and D8247652 (the last one has detailed explanation of the problem).
From this commit I propose that we have to follow simple rule:
If some prop has a default value which differs from the default value of its type, we have to specify it as {<value>} in .h file and explicitly in .m file, for all other props the default value must not be specified explicitly (in .h files it must be specified as {}).
The reason is that we have to embrase those cases and establish behaviour: if we change the default value in .h file, it always means that we have to change the value in .cpp file too.

This diff changes how we store and manage Yoga Config in layoutable shadow nodes.
Previously we have `shared_ptr` to single shared yoga config (one to many relationships); now we initiate and store yoga config with yoga node (one to one relationship).
Cons:
- Less memory efficient.
Pros:
- Much more flexible model. Configuration can be tweaked on a per-node basis.
- More performant. Dealing with `shared_ptr` is expensive because of atomic ref-counter. (This is not really applicable for the previous approach but would be applicable for any alternate approach where we want to have more granular control of the configuration.) Data locality is also great in the new model which should positively impact performance.
- Simplicity. Any alternate approach where we manage sets of nodes which share the same configuration is going to be quite complex.

Summary:
Just definition; we don't have an implementation on the native view layer yet.
And we don't have `transform` prop yet (because it's quite complex).

This is pretty straightforward implementation uses native `UISwitch`.
Suddenly we need Switch to test a bunch of other things.

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: 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.

Summary:
* numbers in JS are doubles in native land, since there's no notion of int or int64 in JS - so simply convert numbers to int instead of assuming it's int
* the parsing of Yoga props with `'...%'` string value has a bug: it should be copying the number instead of the `%`

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.
