2a3025da97 Fabric: Application layer of events infrastructure
Summary: This implements `EventHandlers` abstract class (aka "Events Guy") which encapsulates `eventDispatcher` and `instanceHandle` (and ownership of future `eventTarget`), all of this as part of existing {ShadowNode + Props + LayoutMetrics + LocalData + Descriptor + (and now) EventHandlers} infra. (We don't plan to add anything else to this model. Ever.)

8f507280ac Fabric: Removing default arguments from ShadowNode's constructors
Summary: We don't use them at all; moreover they complicate adding/changing signatures of those methods (because arguments with defaults must be grouped at the end and some arguments cannot have defaults).

dd3a6eda70 Fabric: Devirtualizing of props parsing infra
Summary:
This diff contains several tight to each other changes (which can/should not be split into several diffs):
 * 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.

6bbc2ec921 Fabric: Introcucing ConcreteComponentDescriptor::adopt()
Summary: Overriding `adopt` method allows subclasses to configure just created or cloned shadow nodes without overriding `create` and `clone` methods.

bd91eaf664 Fabric/Text: ShadowNode::clone() - dynamic self-cloning mechanism
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.

6924d44b20 Fabric: Fixed ConcreteShadowNode::getProps()
Summary:
Apparently, there is no point to return a reference from this method because the struct (std::shared_ptr) is allocated on stack.
The test is also updated.
