56501dcc47 Fabric: Changing the shape of ShadowViewNodePair class
Summary:
I am not sure why it compiled before, it clearly should not, IMO. The `const` types (and references!) are not allowed inside `std::vector` because they are not assignable.
Some experiments that I did caused compilation errors here, so I am changing that to be actually correct.

cf2a289372 Fabric: Remove designated initializers in Events and Mounting (#23441)
Summary:
This pull request removes the designated initializers in `react/mounting/**` and `react/events/**` to improve portability.

A destructor was also defined for `ShadowView` to fix this error:

```
ShadowViewMutation.cpp:14: error: undefined reference to 'facebook::react::ShadowView::~ShadowView()'
ShadowViewMutation.cpp:24: error: undefined reference to 'facebook::react::ShadowView::~ShadowView()'
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
```

[General] [Changed] - Fabric: Remove designated initializers in Events and Mounting

802534e611 Fabric: Introducting State, an escape path from unidirectional data flow
Summary:
In React Native there are several use cases where React State is not the only input that affects the component tree. E.g., in case of a <Modal> component, the screen size directly affects the layout of components inside modal; in the case of uncontrolled <TextInput> component, the text inside the input affects the layout of the surrounding components. `State` is a special (legit!) workaround for all those similar cases. Native part of React Native maintains a special shared object between all nodes of the same family and use that during cloning and commits.

See coming commits to know how to use that.

In the near future State will fully replace LocalData concept but for simplicity they both exist for now.

9a64755a18 Fabric: events module was merged into core module
Summary: That's bummer that we have to do it, but it's actually reasonable. Files in `core` and `events` depend on each other creating circular dependencies and other similar hard problem.

a9049442f7 Fabric: Use LRU to cache results of ParagraphShadowNode::measure
Summary: Use a folly LRU implementation to cache results of ParagraphShadowNode::measure, which Yoga asks for repeatedly. Should have a substantial speed improvement on Android and iOS, or at least that's the dream.

62173a1569 Introducing fabric/mounting module
Summary:
ShadowView, ShadowViewMutation, and Differentiator were decoupled to separate module.
That enables us to use ShadowView more widely without facing a circular dependency problem.
