[ios, macos] Make Xcode 7.3 the minimum required version

- Removes nullability shims for Xcode 6.
- Removes MGLTypes.h from files where it was only being used for
  nullability support.
- Accepts that `NS_SWIFT_NAME` is not fully supported by Xcode 7.2 and
  lower.
- Adds documentation about Xcode 7.3 requirement.

 * A new runtime styling API allows you to adjust the style and content of the base map dynamically. All the options available in [Mapbox Studio](https://www.mapbox.com/studio/) are now exposed via MGLStyle and subclasses of MGLStyleLayer and MGLSource. ([#5727](https://github.com/mapbox/mapbox-gl-native/pull/5727))

+* Xcode 7.3 or higher is now required to use this SDK. ([#6059](https://github.com/mapbox/mapbox-gl-native/issues/6059))
 * Simulator architecture slices are included in the included dSYM file, allowing you to symbolicate crashes that occur in the Simulator. ([#5740](https://github.com/mapbox/mapbox-gl-native/pull/5740))
