[ios, macos] Undeprecated unversioned style URL factory methods

Undeprecated the unversioned style URL factory methods in MGLStyle for consistency with the Android and Qt SDKs. Added warnings about using them with the runtime styling API.

Refactored mbgl::util::default_styles to track different versions for different styles.
