Valentin Shergin d49ebbcf62 Fabric: All *EventHandlers were renamed to *EventEmitter
Summary:
Using `EventHandlers` name was a bad idea, and I cannot tolerate it anymore.
The worst part of it is that when you have a collection of `EventHandlers` objects you cannot use plural word to describe it because `EventHandlers` is an already plural word.

And, this object is actually an event emitter, the thing on which we call events.

Valentin Shergin 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.)

Valentin Shergin 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).

Valentin Shergin 120dcec621 Fabric: New props treatment in `core` module
Summary:
Same as previous one.
Adopting template-generated `convertRawProp` and `debugStringConvertibleItem` functions in `core` module.
Note, to do so we have to change signatures of some conversions functions to make them more overloading-friendly.

Valentin Shergin 7048c9134a Fabric: Support for optionals in `convertRawProp` and `debugStringConvertibleItem` templates
Summary:
We have to have automatic treatment for `optional` types. So, if we can process type `T` we can also automatically process `optional<T>.`
Support for optional allows us to not introduce new types (with embedded special "undefined" value) or pollute existing pure types (with special "undefined" value). (A lot of examples of those types can be found in AttributedString module.)

Valentin Shergin 03fb77cc95 Fabric: Using templates to generate convertRawProp and debugStringConvertibleItem functions
Summary:
This diff opens a diffstack where we migrate the generation of all prop conversions (convertRawProp) and pretty-printing (debugStringConvertibleItem) functions to C++ templates (instead of using `#define`s).
So, this diff implements base versions of those functions as templated functions.
For now we still need #define-based version, but eventually, we will get rid of it.

Valentin Shergin 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.
