This does a pass to clean them all up, ignore generated files, and refactor some code to be... better.

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.
## Changelog
[General] [Added] - Added PlatformColor implementations for iOS and Android
Pull Request resolved: https://github.com/facebook/react-native/pull/27908

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail.

Summary: We are working to remove additional types and eventually define everything at the top level as a public exported type of react-native. I was able to update callsites by just using ViewStyleProp in places that were expecting a prop of just one of these. It is a little bit weaker, but much simpler. If a callsite wants to only take margin, it should just take a margin prop instead of a LayoutStyle prop.

Summary:
Issue [#2088](https://github.com/facebook/react-native/issues/2088).
The basic desire is to have a declarative mechanism to transform text content to uppercase or lowercase or titlecase ("capitalized").
My test plan involves having added a test-case to the RNTester app within the `<Text>` component area. I then manually verified that the rendered content met my expectation.
Here is the markup that exercises my enhancement:
```
<View>
<Text style={{ textTransform: 'uppercase'}}>
This text should be uppercased.
</Text>
<Text style={{ textTransform: 'lowercase'}}>
This TEXT SHOULD be lowercased.
</Text>
<Text style={{ textTransform: 'capitalize'}}>
This text should be CAPITALIZED.
</Text>
<Text style={{ textTransform: 'capitalize'}}>
Mixed:{' '}
<Text style={{ textTransform: 'uppercase'}}>
uppercase{' '}
</Text>
<Text style={{ textTransform: 'lowercase'}}>
LoWeRcAsE{' '}
</Text>
<Text style={{ textTransform: 'capitalize'}}>
capitalize each word
</Text>
</Text>
</View>
```

Summary:
Changed StyleSheet.create to be the identity function. We no longer hide it behind an opaque number. Better for types and perf since we don't use it.
I don't really know if we have/need any safer way of rolling this out than just landing it.
It can break if the object passed to StyleSheet.create is mutated afterwards but that isn't a practice anywhere I've seen.
