[core, android, ios, macos] Added Traffic Day/Night to default styles

The Styles API section of the Mapbox API Documentation site now lists Traffic Day v2 and Traffic Night v2, so this change adds those styles to all the places where styles are listed.

Also switched iosapp and macosapp to unversioned style factory methods since MGLStyleDefaultVersion is no longer applicable for all styles.

Cherry-picked from 4d6f54553d277c0af24a0b8ff03d2dd7e9284ca2.
