Changelog:
[Internal] - The accessibilityRole will be used to specially distinguish normal fragments and fragments with embedded link, which is helpful when building accessibilityElement.
According to this document: https://reactnative.dev/docs/accessibility, the accessibilityRole is a common accessibility props that could be inherited, and this is why I add accessibilityRole to the TextAttributes.

Summary:
This diff extends the measurement of Text components in order to support empty strings.
This is required for parity with Paper.
I created a follow up task to analyze support of empty string as part of the Text infrastructure of Fabric in the future.

Summary:
`BaseTextShadowNode::getAttributedString()` was replaced with simular method `BaseTextShadowNode::buildAttributedString()` which does same work with following differences:
* Besides returning `AttributedString`, it retures an array of `Attachment`s elements of which points to `ShadowNode`s that form attachments;
* Now we use single `AttributedString` to construct result instead of concatenation objects recurvily walking the tree.
We will use the array of attachments later.

Summary:
Clearing `props` and `state` (which we don't use) allows avoiding retain cycles.
The memory leak was caused by a retain cycle:
AttributedString -> Fragment -> ShadowView -> PharagraphState -> TextLayoutManager -> Cache -> AttributedString.
We don't use `props` and `state` parts of `ShadowView` inside `AttributedString`.

Summary:
Having the overridden function that returns a different type is apparently not a good idea (and might cause bugs and unexpected behavior), so it was renamed. The function also got a new return type (`const &` instead of `std::shared_ptr`) for simplicity, better performance, and smaller code size.

Summary:
Motivation: in Marketplace, there's a TextInput in JS that sends { lineHeight: null } to C++. In Paper this was correctly handled as a default value, which just causes that property to not be set. In C++ in Fabric, it was being parsed incorrectly as 0 (because of incorrect defaults being passed into `convertRawProp`), causing the text to not be visible at all. The solution is to make sure that its default value is NaN, which is handled correctly, and causes the Text to render again.

Summary:
Before this change `AttributedString::Fragment` had two ShadowView objects (`shadowView` and `parentShadowView`). This diff unifies those two things into one. That allows us to save some CPU and memory and makes things a bit simpler. Besides that, now the length of NSAttributedString and AttributedString is now always the same (it's one Unicode character for an attachment for both).

Summary:
This is another step on the journey of removing `enable_shared_from_this`.
It's unclear why we used that before but it's clear now that using shared_ptr here is not necessary because all computation around happens inside the single callstack, so by definition we don't have object life-time concerns here.

Summary:
Consider this:
* ParagraphShadowNode retains LocalData,
* LocalData contains AttributedString,
* AttributedString contains Fragments,
* Fragment can contain a pointer to parent shadow node, so it can be the ParagraphShadowNode.
In this case it's a retain cycle.
We actually don't need to store pointers to not TextShadowNodes, so we don't now.
Later, after we fully migrate to ShadowView, we can remove this condition because it will become harmless.

All those changes must work *exactly* like it was before.

Summary:
When a user clicks on some text, `RCTSurfaceTouchHandler` will call into a method on `RCTParagraphComponentView`. That method (i.e: `touchEventEmitter`) would be responsible for identifying the closest ancestral `<Text/>` component to which we should dispatch the `onPress` event, given the point where the user clicked. To answer this query, we'll use a data structure called `UIAttributedString`.
This data structure represents a string, and a corresponding mapping from sequences of its characters to some arbitrary data. In this attributed string, we'll map sequences of characters to their closest ancestral `ParagraphShadowNode` or `TextShadowNode`. That way, when we get a click event on `RCTParagraphComponentView`, we can just look at the character that was clicked, and use that information to do a lookup in the attributed string to find the shadow node who's EventEmitter is responsible for processing the click event.

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).
