Summary: Storing a strong shared pointer to `ComponentDescriptor` can cause a memory leak. Therefore we enforce all call sides and params to be weak pointers. The only Scheduler preserves a retaining pointer to it (to prevent preliminary deallocation).

All props to Eric Lewis! cc ericlewis
This revert of revert of land of changes originally published in #24873 (with some slight fixes). The change removes usage of LocalData from the `<Text>` component.
After this change we only have ---one (maybe two)--- three components left using LocalData.

Summary:
With recent changes, simple cloning a component does not mean that underlying Yoga node will be dirtied. Autodirtying is only performed if the child nodes were dirtied and/or if the YGStyles were changed.
That's not the case for Text component which does not have direct layotable children, so we have to call `dirtyLayout` explicitly.

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.

I was watching a classic magnificent talk about modern C++ by Herb Sutter and I was totally sold on double down on using `auto` in our codebase. Surprisingly, 95% of the code base already follows Herb's guidence; I just changed the last 5% to make it consistent.
All those changes must work *exactly* like it was before.

Summary:
This diff includes two changes:
1. `TextShadowNode` represents virtual texts. For the time being, virtual text nodes only need touch capabilities so that they can handle `onPress` events for their children. Therefore, we should set the `TextShadowNode`'s `EventEmitterT` to `TouchEventEmitter`.
2. Since `ParagraphShadowNode` extends an instance of the `ConcreteViewShadowNode` template, it automatically uses the `ViewEventEmitter` if no event emitter is specified. I think it's better to make the event emitter explicitly specified. So, I've included that change in this diff.

Summary: Previously, `BaseTextShadowNode::getAttributedString` used to recurse on a list of `SharedShadowNode`s (i.e: the children). In the `RawText` base case of this recursion, we'll need to record the parent of the current `RawText` (so that we can dispatch the `onPress` event to it). Therefore, we need to start recursing using the `SharedShadowNode` itself, and not its children.

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).
