New dark mode features

· Added a new Appearance module to provide access to the user's appearance preferences, such as their preferred color scheme (light or dark).

const colorScheme = Appearance.getColorScheme()

if (colorScheme === 'dark') {
  // Use dark color scheme
}

· Added a hook to subscribe to state updates to the users preferences:

import { Text, useColorScheme } from 'react-native'

const MyComponent = () => {
  const colorScheme = useColorScheme()
  return <Text>useColorScheme(): {colorScheme}</Text>
}

Moving Apple TV to react-native-tvos
