Previously, we amitted `default` argument in `convertRawProp` functions assuming that all default values are equal to results of their default constructors (which was something between "wrong" and "lucky coincidence"). Now we use a `YGStyle` default value as a source of all semantic default values of all layout props/styles.

Voalá, this small change actually implements view flattening. Obviously, it does not work right now because there are no `ShadowNode` classes which implement `isLayoutOnly`.
Surprisingly, correct implementing of `isLayoutOnly` is quite tricky, we will work on this in coming diffs.

Summary:

This is quite a big diff but the actual meaningful change is simple: now we use ShadowView class instead of ShadowNode in mutation instructions.
Note:
* In some places (especially during diffing) we have to operate with ShadowNodeViewPair objects (which represents a pair of ShadowNode and ShadowView). The reason for that is that we cannot construct child ShadowViews from parent ShadowViews because they don't have any information about children.
* `ShadowTree::emitLayoutEvents` is now much simpler because ShadowView better represents the specifics of this kind of object.
* The code in RCTMountingManager also became simpler.
This change will allow us to implement more cool tricks soon.

Summary:

We need some another object like ShadowNode (but not ShadowNode) to represent an instance of the component in the mutation instructions. This is
the main motivation for introducing ShadowView.
Why not use ShadowNode? ShadowNode is designed to represent a node in ShadowTree, not be a part of a mutation instruction.
* ShadowNode exposes some APIs that should not be exposed to the mounting layer;
* ShadowNode is an immutable data structure, so we cannot mutate it in some way which can be meaningful for mounting;
* We should not add to ShadowNode any functionality which is needed only for mounting;
* ShadowNode is a bit more heavy object to share that it needs to be; it's exposed (embedded into Mutation) as a `shared_ptr` which is not optimal from the performance perspective;
* Retaining ShadowNode from mounting code can unnecessarily extend its lifetime which can negatively affect memory usage.

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.

Summary:

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).
