Now we use same data structure to specify a shape of shadow node as we use in ShadowNode (sub)clases.

Summary:
@public
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).

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.)

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.

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").
