Summary:
Now ConcreteComponentDescriptor can infer `ComponentName` from `ShadowNodeT` automatically,
so in the most cases we even don't need to create a subclass of that.

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.)

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.

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:
I was shamed by Sebastian's sebmarkbage concerns (totally unrelated to this topic) about introducing another level of indirection into the system and decided to change my original plan not to support text attributes for the <Paragraph> component.
So, now <Paragraph> shares <View>, <Text> and <Paragraph> itself capabilities. That reduces the minimum amount of required components for trivial text fragment from three (Paragraph, Text, RawText) to two (Paragraph and RawText).
Special thanks for C++ for supporting multiple inheritance.

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").
