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
Test Plan:
The changes have been tested using the RNTester test app for iOS and Android. On iOS a set of XCTestCase's were added to the Unit Tests.

In addition `PlatformColor` support has been added to other out-of-tree platforms such as macOS and Windows has been implemented using these changes:
react-native for macOS branch: https://github.com/microsoft/react-native/compare/master...tom-un:tomun/platformcolors
react-native for Windows branch: https://github.com/microsoft/react-native-windows/compare/master...tom-un:tomun/platformcolors

Summary:
Originally, normalizeColor.js was in Library/Color/ however, I noticed that its tests were in a completely different directly (Library/StyleSheet/__tests__) which was confusing. The other files such as processColor.js, setNormalizedAlphaColor.js had their tests in Library/StyleSheet/__tests__ as well.
## Changelog
[Internal] [Changed] - Moved normalizeColor.js to a more appropriate directory where its tests live.
Pull Request resolved: https://github.com/facebook/react-native/pull/27372
Test Plan: I simply moved a file and changed dependencies. The code should still function as is.

Summary:
The hex8 specified version is #rrggbbaa so it would be great to have the internal representation be 0xrrggbbaa to prevent confusion.
This pull request changes the internals of normalizeColor. It changes a lot of lines but there isn't any big changes.
Small changes:
- Use | instead of + for number operations
- Use x << 24 instead of x * (1 << 24)
- Have hslToRgb return pre shifted number
processColor is still sending colors the 0xaarrggbb format to native and tests still pass without changes.

Summary:
Animating colors using Animated is currently interpolating rgb and rgba and doesn't round the intermediate values. We need to fix it there but it's not a straightforward change so reverting to the lax version here until we fix it inside of Animated (which is needed to work on web anyway).

Summary:
**Problem:**
As I was trying to document what color formats we supported, I realized that our current implementation based on the open source project tinycolor supported some crazy things. A few examples that were all valid:
```
tinycolor('abc')
tinycolor(' #abc ')
tinycolor('##abc')
tinycolor('rgb 255 0 0')
tinycolor('RGBA(0, 1, 2)')
tinycolor('rgb (0, 1, 2)')
tinycolor('hsv(0, 1, 2)')
tinycolor({r: 10, g: 10, b: 10})
tinycolor('hsl(1%, 2, 3)')
tinycolor('rgb(1.0, 2.0, 3.0)')
tinycolor('rgb(1%, 2%, 3%)')
```
The integrations of tinycolor were also really bad. processColor added "support" for pure numbers and an array of colors!?? ColorPropTypes did some crazy trim().toString() and repeated a bad error message twice.
**Solution:**
While iteratively cleaning the file, I eventually ended up reimplementing it entierly. Major changes are:
- The API is now dead simple: returns null if it doesn't parse or returns the int32 representation of the color
- Stricter parsing of at
