Now it accepts `const ShadowNode &` instead of `std::shared_ptr<const ShadowNode>` which is more reasonable (and more performant) becasue the function must not retain ownershipt.

When we copy-construct ShadowNode, we don't need to retain a source shadow node, so there is no need to pass it as a `shared_ptr`. Passing an argument to constructor as `const &` is also more idiomatic in C++.

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).

This diff changes a way how we specify a shape of newly created and/or cloned of ShadowNode. Previously we pass those values as a list of arguments, now those values are coupled into a new data structure called ShadowNodeFragment. All that makes suppose to make code much more easy to read and maintain, this is especially important because we want to add a couple of new entities in this set.

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).

Previously, ContextContainer could store only `shared_ptr`s, but now it wraps all values in own `shared_ptr` container.
I wish we can use `unique_ptr` here, but apparently we cannot because `unique_ptr` does not support type-erasure (`std::unique_ptr<void>` is illigal).
Becasue ContextContainer is not supposed to be used in hot paths, the performance aspect of that does not actually matter.

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.
