While it would be better to be able to do all of the ownership metadata at the Buck macro level, that proved to be more work than expected.
This diff adds the corresponding pfh label to all targets in `xplat/js/react-native-github` that have a Supermodule label. Once the migration is complete the Supermodules labels will be able to be removed.

You can read more about this rule on https://clang.llvm.org/extra/clang-tidy/checks/modernize-pass-by-value.html
# Isn't it wasteful to copy? Isn't reference more efficient?
This rule of thumb is no longer true since C++11 with move semantics. Let's look at some examples.
# Option one
```
class TextHolder
{
public:
TextBox(std::string const &text) : text_(text) {}
private:
std::string text_;
};
```
By using reference here, we prevent the caller from using rvalue to and avoiding copy. Regardless of what the caller passes in, copy always happens.
# Option two
```
class TextHolder
{
public:
TextBox(std::string const &text) : text_(text) {}
TextBox(std::string &&text) : text_(std::move(text)) {}
private:
std::string text_;
};
```
Here, we provide two constructors, one for const reference and one for rvalue reference. This gives the caller option to avoid copy. But now we have two constructors, which is not ideal.
# Option three (what we do in this diff)
```
class TextHolder
{
public:
TextBox(std::string text) : text_(std::move(text)) {}
private:
std::string text_;
};
```
Here, the caller has option to avoid copy and we only have single constructor.

For some reason, using `TextLayoutManager::Shared` in `TextInputShadowNode` trips up clang tidy linter. We have a plan to move away from `*::Shared` anyway, so let's remove it from `TextInputShadowNode` now.
Why do we want to move away from `*::Shared`?
Using `TextLayoutManager::Shared` is confusing for people unfamiliar with Fabric's codebase. It expresses a concept of immutability but uses term `shared`. Term shared is already used in C++ `std::shared_ptr`.

Summary:
Fabric uses a cache where it stores the result of the text measurement in C++ (to avoid unnecessary text measurement that are very costly). This cache has a "max size" of 256 and this size is not enough to store all the texts we have in the screen
In my tests, the amount of texts being measured are ~290 and after scrolling many times they increase to 611.
This diff increases the size of the TextMeasure to 1024 for users in the experiment. As a result this improves performance of HoverEvents by +5x times (see test plan)

The [first implementation of `TextAttributes` in Fabric](https://github.com/facebook/react-native/commit/62576bcb7832e08c6fd9f9482285882c37a2ece5) included two separate props instead of `textDecorationStyle`: `textDecorationLineStyle` (single, double, ...) and `textDecorationLinePattern` (dot, dash, dotdash, ...). These two props were implemented in C++ and iOS but never supported in JS.
Pre-Fabric (and CSS) on the other hand use a single prop `textDecorationStyle: 'solid' | 'double' | 'dotted' | 'dashed'`.
This diff implements this same API in Fabric, and removes the unused `textDecorationLineStyle` and `textDecorationLinePattern` props.

3. Return sane defaults so that prod cases don't crash, and don't return totally garbage data.

Summary:
The is how it works:
* Text is a quite special component with special properties and constraints. Some of them are:
It's expensive to measure (layout) text. It's expensive to measure and expensive to pass AttributedString via JNI.
* When we measure text, we don't concerned about maximum height, only maximum height is important. (Even though theoretically, there are text layout systems that can balance these constraints (max height and width) trying to find a perfect result, we don't use such complex (and expensive) layout engines for building UIs).
Yoga, as a flexbox engine, does not aware of such constraints, so it requests remeasuring of text components quite often, so we have an RN built-in text measure cache system just for text measurements that suit these constraints. This way when Yoga requests a text measuring, we always measure with `Inf` height and store that result in the cache. And when Yoga requests another measure with the same width but a different height we retrieve the value from the cache and then just clamp it.

Summary:
This diff fixes a bug in the calculation of layout for text components
The rootcause of the bug is that fabric is not taking into consideration height constraints as part of the cache for text measurments.
The title text was being measured with a specific height constraint (22px) at the begining of the render, later there was a re-measure for the same Text component with a different height constraint, but fabric was reusing the result of the first calculation instead of re-measuring the text.

Summary:
There are a few places where we have JNI table ref leaks, and more places where we can aggressively clean up smart pointers immediately instead of waiting for them to be cleaned up at some later point.
In theory these smart pointers should be cleaned up immediately, but in cases where many components are being measured at once, the JNI table could grow until all measure calls are done. In extreme cases this
could cause a crash, which I want to avoid. At the very least, freeing memory more aggressively in this case can't hurt.

Summary:
This change maps the three most used colors (black, white, clear) to corresponding predefined values in UIColor. This should meaningfully reduce the overall amount of allocated UIColor/CGColor objects. In my non-scientific measures, it reduces the number of CGColor objects from ~1500 to ~1000. And... it no much at least in terms of kilobytes. However, I still think it's a good idea to implement this because I hope that can remove some work from memory allocation infra and maybe enable some optimizations that UIKit hopefully does for black and white colors. (I tend to believe that this optimization exists because UIKit even has a classes called UIDeviceWhiteColor and UICachedDeviceWhiteColor.)

Instead, the methods just extract color components from SharedColor and create UIColor and CGColorRef objects on demand.
This allows us to change the implementation of SharedColor without worrying much about the rest of the system, which will do in the next diff.
