Summary:
This change removes the `ColorAndroid` API. It was added more as a validation tool than as something useful to a developer. When making the original [PlatformColor PR](https://github.com/facebook/react-native/pull/27908) we felt it was valuable and useful to have working platform specific methods for the two platforms in core to test that the pattern worked in app code (PlatformColorExample.js in RNTester) and that the Flow validation worked, etc. Practically `PlatformColor()` is more useful to a developer on Android than `ColorAndroid()`. Now that the construct has served its purpose, this PR removes the `ColorAndroid` function and its related tests and other collateral.

Summary:
The [PlatformColor PR](https://github.com/facebook/react-native/pull/27908) added support for iOS and Android to express platform specific color values. The primary method for an app to specify such colors is via the `PlatformColor()` method that takes string arguments. The `PlatformColor` method returns an opaque Flow type enforcing that apps use the PlatformColor method instead of creating Objects from scratch -- doing so would make it harder to write static analysis tools around Color values in the future. But in addition to `PlatformColor()`, iOS has a `DynamicColorIOS()` method that takes an Object. The Flow type for this Object cannot be opaque, but we still want to enforce that app code doesn't pass variables instead of Object literals or that values in the Objects are variables. To ensure `DynamicColorIOS()` can be statically analyzed this change adds an ESLint rule to enforce that `DynamicColorIOS()` takes an Object literal of a specific shape. A `ColorAndroid()` was also introduced not for practical use but just to test having platform specific methods for more than one platform in the same app. A second ESLint rule is created for `ColorAndroid` as well.

Summary: Ports an internal ESLint rule used at Facebook, `error-subclass-name`, to cover the React Native codebase. This rule enforces that error classes ( = those with PascalCase names ending with `Error`) only extend other error classes, and that regular functions don't have names that could be mistaken for those of error classes.
