* [ios, macos] new struct MGLTransition

* [ios] MGLTransition struct moved to MGLTypes.h

* [ios] MGLTransition implemented for style layer properties

* [ios, macos] added support for getting property transitions

* [ios, macos] updated to MGLDurationFromTimeInterval and MGLTimeIntervalFromDuration

* [ios, macos] added transition properties test

* [ios, macos] modified key strings imp

* [ios, macos] The impl for transition properties were changed to public methods

* [ios, macos] Changelog update

* [ios] Fixed layer space formatting

* [core] The name space was fixed for getters that returned TransitionOptions

* [ios, macos] Added rawLayer transition property tests

* [ios] Added a factory method for MGLTransition and transition-related methods to NSValue(MGLAdditions)

* [ios, macos] Copyedited changelog blurbs about transition properties
