Add structural counterparts for Locale, Calendar, and Timezone

`description(withLocale:)` now takes `Locale?` instead of `AnyObject?` to prevent needless bridges

`NSRange` now uniformly converts to `Range<Int>` instead of `CountableRange<Int>` (in pairity with the Darwin version)

NSCalendar has a few nullability changes to more closely represent how the Darwin version works

And bridging types to CF have been adjusted to their NS counterparts
