[ios, macos] Fix map load error descriptions (#8466)

* [ios, macos] Corrected map load error descriptions

Ensured the uniqueness of localizable string IDs. Ran make genstrings to add the -[MGLMapViewDelegate mapViewDidFailToLoad:withError:] error description strings to the base localization.

* [ios, macos] Moved failure error changelog entry to new release
