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).
