Summary:
Right now nested Text components are not accessible on Android. This is because we only create a native ReactTextView for the parent component; the styling and touch handling for the child component are handled using spans. In order for TalkBack to announce the link, we need to linkify the text using a ClickableSpan.
This diff adds ReactClickableSpan, which TextLayoutManager uses to linkify a span of text when its corresponding React component has `accessibilityRole="link"`. For example:
<Text>
A paragraph with some
<Text accessible={true} accessibilityRole="link" onPress={onPress} onClick={onClick}>links</Text>
surrounded by other text.
</Text>
With this diff, the child Text component will be announced by TalkBack ('links available') and exposed as an option in the context menu. Clicking on the link in the context menu fires the Text component's onClick, which we're explicitly forwarding to onPress in Text.js (for now - ideally this would probably use a separate event, but that would involve wiring it up in the renderer as well).
ReactClickableSpan also applies text color from React if it exists; this is to override the default Android link styling (teal + underline).

Summary:
This fixes TextInput measurement caching. Previously we were not setting the correct Spannable in the cache; we needed to additional Spans to it to indicate font size and other attributes.
This brings Fabric closer to how non-Fabric was measuring Spannables for TextInputs (see ReactTextInputShadowNode.java).
This should fix a few crashes and will be most noticeable with dynamically-sized multiline textinputs where the number of lines changes over time.
This also allows us to transmit less data from C++ to Java in the majority of cases.

Summary:
Simplify the TextInput measurement mechanism.
Now, data only flows from JS->C++->Java and from Java->JS. C++ passes along AttributedStrings from JS if JS updates, and otherwise Java maintains the only source of truth.
Previously we tried to keep all three in sync. This was complicated, slow, and even lead to some crashes.
This feels a bit hacky but I believe it's the simplest way to achieve this short-term. Ideally, we would use something like `AttributedStringBox` and pass that to State from Java,
but currently everything passed through the State system from Java must be serializable as `folly::dynamic`. So, instead, we just cache one Spannable per TextInput component and
use ReactTag as the cache identifier for lookup.
An interesting side-effect is that `measure` could race with TextInput updates, but the race condition favors measuring the latest text, not outdated values.
Followups:
- Can we do this without copying the EditText Spannable on every keystroke? Maybe this approach is too aggressive, but I don't want a background thread measuring a Spannable as it's being mutated.
- Do we need to support measuring Attachments?
- How can we clean up this API? It should work for now, but feels a little hacky.

Summary:
When text is in a constrained parent view using `maxWidth`, long text may wrap. When the text wraps, the final width is dependent on the word breaking strategy and text content. This means that the text width is not necessarily `maxWidth`.
However, the current way that we compute text layout does not shrinkwrap the text width as much as possible. This leads to visual gaps to the end-side of wrapped text.
This changes the text layout slightly so that we use the length of the longest line.
This bug only exists on Android. After this change, Android behaves like iOS.

As a consecuence there was some mistmaches of types during parsing and that was throwing an exception in some examples.

Summary:
This Pull Request implements the PlatformColor proposal discussed at https://github.com/react-native-community/discussions-and-proposals/issues/126. The changes include implementations for iOS and Android as well as a PlatformColorExample page in RNTester.
Every native platform has the concept of system defined colors. Instead of specifying a concrete color value the app developer can choose a system color that varies in appearance depending on a system theme settings such Light or Dark mode, accessibility settings such as a High Contrast mode, and even its context within the app such as the traits of a containing view or window.
The proposal is to add true platform color support to react-native by extending the Flow type `ColorValue` with platform specific color type information for each platform and to provide a convenience function, `PlatformColor()`, for instantiating platform specific ColorValue objects.
`PlatformColor(name [, name ...])` where `name` is a system color name on a given platform. If `name` does not resolve to a color for any reason, the next `name` in the argument list will be resolved and so on. If none of the names resolve, a RedBox error occurs. This allows a latest platform color to be used, but if running on an older platform it will fallback to a previous version.
The function returns a `ColorValue`.
On iOS the values of `name` is one of the iOS [UI Element](https://developer.apple.com/documentation/uikit/uicolor/ui_element_colors) or [Standard Color](https://developer.apple.com/documentation/uikit/uicolor/standard_colors) names such as `labelColor` or `systemFillColor`.
On Android the `name` values are the same [app resource](https://developer.android.com/guide/topics/resources/providing-resources) path strings that can be expressed in XML:
XML Resource:
`@ [<package_name>:]<resource_type>/<resource_name>`
Style reference from current theme:
`?[<package_name>:][<resource_type>/]<resource_name>`
For example:
- `?android:colorError`
- `?android:attr/colorError`
- `?attr/colorPrimary`
- `?colorPrimaryDark`
- `android:color/holo_purple`
- `color/catalyst_redbox_background`
On iOS another type of system dynamic color can be created using the `IOSDynamicColor({dark: <color>, light:<color>})` method. The arguments are a tuple containing custom colors for light and dark themes. Such dynamic colors are useful for branding colors or other app specific colors that still respond automatically to system setting changes.
Example: `<View style={{ backgroundColor: IOSDynamicColor({light: 'black', dark: 'white'}) }}/>`
Other platforms could create platform specific functions similar to `IOSDynamicColor` per the needs of those platforms. For example, macOS has a similar dynamic color type that could be implemented via a `MacDynamicColor`. On Windows custom brushes that tint or otherwise modify a system brush could be created using a platform specific method.

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.
