Summary:
UpdateLocalData and UpdateState return an `extra data` object, which in the case of TextInput contains padding. In Paper, the padding was always set on this object; in Fabric, it generally is not. However, the ViewManager was unconditionally setting the padding on the view, regardless of whether or not padding was set. We just check the padding values before setting now. This fixes an issue where the padding would be reset when the user started typing in Fabric.

Summary:
We are seeing some non-trivial amount of crashes happened because `[RCTSurfacePresenter synchronouslyUpdateViewOnUIThread:props:]` requests a Component Descriptor which does not register in the registry.
And the problem here is that ComponentDescriptors are not being designed to be used outside of C++ UIManager, and we only use that in RCTSurfacePresenter only because it's an old workaround that makes Native Animation Driver works with Fabric.
Messing with ComponentDescriptors are in general dangerous. Accessing them outside of UIManager means that they might be deallocated at any time, extending their lifetime will cause other crashes on the other side. So, that's why this is "BROKEN".
This diff does not make the code worse, it just designates the problem that was there for a long time, so it kinda makes it better.
We don't know for sure why some ComponentDescriptors are not registered but this diff at least makes it not crash in such case.

Summary:
Special thanks for Joshua Gross for flagging this problem!
This diff implements a custom evicting hash map designed specially to hold text measurement information. The key feature of this is custom equality checks and hashing functions.
They are designed around the following principals:
* Decorative text attributes (such as color, shadows, etc) has no effect on layout, therefore they should not be taking into account;
* `minimum height`, `minimum width`, and `maximum height` don't affect the measurement;
* the value of `layout metrics` are important only for `attachment` fragments.
After I redo all tests, I will enable this for Android-specific TextLayoutManager in separate diff.

Summary:
Here the deal with the clamp thing:
A layout engine asks nodes to measure their content providing layout constraints (min and max size) and that would be kind from nodes to return a result that in space of those constraints. Sometimes, satisfying that is an additional separate step of that operation, e.g. if we know that the intrinsic size of some node is `{100, 100}`, we need to clamp that to satisfy constraint `[min: {200, 200}, max: {inf, inf}]`.
In case when we need to cache measure information, it becomes tricky enough when we need to make the cache work most efficiently. For the case of measuring Text, we have an insight: the available maximum width is important, the rest three metrics (maximum height and minimum size) are not.
That means that any changes in those three metrics don't affect the actual measurement result but will affect the final value because the actual value will be clamped by constraints that didn't influence measuring in the first place.
That's why moving clamping outside of a cache is the first step into making it more efficient.

Summary:
## Context
`NativeModuleRegistryBuilder` calls `TurboReactPackage.getNativeModuleIterator()` to access ModuleHolders for all the NativeModules in the `TurboReactPackage`. We then filter out the ModuleHolders that contain `TurboModules`, before using that list to make create the `NativeModuleRegistry`.
## Problem
Creating `ModuleHolders` has the side-effect of actually creating the NativeModule if it requires eager initialization. See [ModuleHolder.java](https://fburl.com/diffusion/4avdtio0):
```
class ModuleHolder {
// ...
public ModuleHolder(ReactModuleInfo moduleInfo, Provider<? extends NativeModule> provider) {
mName = moduleInfo.name();
mProvider = provider;
mReactModuleInfo = moduleInfo;
if (moduleInfo.needsEagerInit()) {
mModule = create(); // HERE!
}
}
```
So, we need to filter out TurboModules before we even create ModuleHolders.

Summary:
The TurboModuleManagerDelegate now supports a `getEagerInitModuleNames()` method, which is supposed to return a `java.util.List` containing the names of all NativeModules that require eager initialization. The NativeModuels are created when the `TurboModuleManager` is created. This happens inside `ReactInstanceManager.createReactContext` slightly after the NativeModuleRegistry is created, which is when our legacy NativeModules are eagerly initialized.
All NativeModules declared in `TurboReactPackages` that are wired into the `TurboModules` infra via `ReactPackageTurboModuleManagerDelegate` can use the `ReactModule(needsEagerInit = true)` annotation. Our build pipeline should correctly process the annotation into a `ModuleInfo`, and `ReactPackageTurboModuleManagerDelegate` should correctly forward the eagerly initialized module names to TurboModuleManager.

Summary:
Before this change, C++ couldn't propagate changes that updated TextInputs that were completely empty. In C++ the AttributedString cannot contain Fragments with empty text, so a completely empty TextInput would have no Fragments; this breaks the C++ state value updating infra since it relies on copying over existing fragments.
Instead, now we propagate default TextAttributes and ShadowView through State, so that State updates can use them to construct new Fragments.

Summary:
Support for modifying AndroidTextInputs with multiple Fragments was added on the Java side in a previous diff.
This diff adds support on the C++ side for the following scenario:
A <TextInput> is initially given contents via children <Text> notes, which represents multiple Fragments (that could have different TextAttributes like color, font size, backgroundcolor, etc). The Android EditText view must get this initial data, and then all updates after that on the Android side must flow to C++ so that the C++ ShadowNode can perform layout and measurement with up-to-date data.
At the same time, the <TextInput> node could be updated from the JS side. All else equal, this would cause the native Android EditText to be replaced with the old, original contents of the <TextInput> that may not have been updated at all from the JS side.
To mitigate this, we keep track of two AttributedStrings with Fragments on the C++ side: the AttributedString representing the values coming from <TextInput> children, from JS (`treeAttributedString`); and the AttributedString representing the current value the user is interacting with (`attributedString`). If the children from JS don't change, we don't update Android/Java with that AttributedString. If the children from JS do change, we overwrite any user input with the tree from JS.

Summary:
When the TextInput is updated on the Java side, make sure C++ State gets updated. We do this by making sure that the AttributedString data-structured in mirrored in Java and in C++.
In practice, the AttributedString is copied into Java a few times during initialization, and then after then, 99% of the time Java is writing without receiving updates from C++. This means that we should optimize the Java-to-C++ update path most aggressively in the future.
However, it turns out that for now, at least, we can't reuse NativeWritableMaps/NativeWritableArrays because they're consumed on the C++ side and can't be modified after that. This is a perf improvement for the future.
This allows us the user to edit any fragments, and the changes will flow through C++ State. This also allows us to edit across multiple Fragments.

Summary:

It turns out that any time props or state change, two `parentShadowView`s will never be equal to each other, even if we'd consider them equal for our use-cases here for AttributedStrings. Just compare the tags instead of the whole object.
NOTE: I don't have any strong opinions about how we should be comparing them. It just isn't working currently for AndroidTextInput. Comparing tags seems convenient and reasonably correct for now.

If the background color has opacity, the `text` prop node will not have the correct background because it will be applied twice. Fix it.

Summary:
The diff implements a new class called `AttributedStringBox` that represents an object storing a shared `AttributedString` *or* a shared pointer to some opaque platform-specific object that can be used as an attributed string. The class serves two main purposes:
- Represent type-erased attributed string entity (which can be platform-specific or platform-independent);
- Represent a container that can be copied with constant complexity.
Why? Several reasons:
- Sometimes it makes sense to keep an attributed string as a shared resource. This way we don't need to pay for expensive copying and we also implement a copy-on-write semantics on top of that if needed.
- We need to extend a TextLayoutMeasure API to support measuring some platform-specific attributed string implementation to remove the necessity of converting a string back and forth between representations. That's especially important for TextInput because we will need to measure that very efficiently (and the source of measuring, in this case, is a platform attributed string).
In other words, we need something to store inside TextInputState to measure and update very efficiently. The source of this data might be a native TextInput control or a data from React, to represent that kinda object we need this data structure (and interfaces that deal with it).

I'm standardizing on `registerLazyCallableModule` so that it will be easier to swap out the implementation later for bridgeless mode.
The only reason I could think why we wouldn't want to do this is if we're relying on some side effect of `require('HMRClient')` when setting up JS, but there don't seem to be any side effects in that module that I can see.

Summary:
The former implementations of `TouchableHighlight` used `defaultProps` for `underlayColor`. However, the newly landed implementations use `??` which falls back to the default behavior if the prop is `null`.
This restores the former behavior so that, for example, supplying `underlayColor={null}` to `TouchableHighlight` will not fallback to black. (It probably should always have, but the intention of my rewrite was not to introduce a breaking change.)
Changelog:
[General] [Fixed] - Restore behavior for `underlayColor={null}` in `TouchableHighlight`.
