[ios, macos] Update and reformat documentation for runtime styling (#7475)

* [ios, macos] Optimized changelog for runtime styling

Changelog entries related to style JSON now lead off with the analogous portion of the runtime styling API.

* [ios, macos] Autolink cross-class property references in docs

jazzy can autolink `Class.property` references in documentation comments.

* [ios, macos] Removed extra blank lines

* [ios, macos] Corrected typo in MGLMultiPoint docs

* [ios, macos] Rewrote shape and feature docs

Rewrote documentation about MGLShape, its subclasses, and MGLFeature to emphasize runtime styling uses over annotation uses, associate each type with real-world concepts, cross-reference related style layer classes, and cross-reference related or easily confused shape classes. Links to the GeoJSON specification have been updated to RFC 7946.

* [ios, macos] Expanded style layer docs

With this change, documentation about style layer classes is nominally based on the documentation in the style specification. However, all the existing layer types’ documentation has been overridden to explain what the layer looks like, relate the layer to a real-world concept, and cross-reference related geometry classes. This change also corrects the description of MGLBackgroundStyleLayer, which erroneously stated that the identifier must be “background”, whereas that only happens to be true by default for Studio template styles.

* [ios, macos] Wrap style layer docs

* [ios, macos] Removed unused code

* [ios, macos] Corrected symbol references in docs

* [ios, macos] Corrected typo in abstract class exception

 * 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))
 * MGLMapView’s `styleURL` property can now be set to an absolute file URL. ([#6026](https://github.com/mapbox/mapbox-gl-native/pull/6026))
-* MGLShapeSource objects, as well as GeoJSON sources specified by the stylesheet at design time, now support `cluster`, `clusterMaxZoom`, and `clusterRadius` attributes for clustering point features on the base map. ([#5724](https://github.com/mapbox/mapbox-gl-native/pull/5724))
+* When creating an MGLShapeSource, you can now specify options for clustering point features within the shape source. Similarly, GeoJSON sources specified by the stylesheet at design time can specify the `cluster`, `clusterMaxZoom`, and `clusterRadius` attributes. ([#5724](https://github.com/mapbox/mapbox-gl-native/pull/5724))
 * Added [quadkey](https://msdn.microsoft.com/en-us/library/bb259689.aspx) support and limited WMS support in raster tile URL templates. ([#5628](https://github.com/mapbox/mapbox-gl-native/pull/5628))
-* TileJSON manifests can now specify `"scheme": "tms"` to indicate the use of [TMS](https://en.wikipedia.org/wiki/Tile_Map_Service) coordinates. ([#2270](https://github.com/mapbox/mapbox-gl-native/pull/2270))
+* When creating an MGLTileSource, you can now specify that the tile URLs use [TMS](https://en.wikipedia.org/wiki/Tile_Map_Service) coordinates by setting `MGLTileSourceOptionTileCoordinateSystem` to `MGLTileCoordinateSystemTMS`. TileJSON files can specify `"scheme": "tms"`. ([#2270](https://github.com/mapbox/mapbox-gl-native/pull/2270))
 * Fixed an issue causing abstract MGLMultiPointFeature objects to be returned in feature query results. Now concrete MGLPointCollectionFeature objects are returned. ([#6742](https://github.com/mapbox/mapbox-gl-native/pull/6742))
 * Fixed rendering artifacts and missing glyphs that occurred after viewing a large number of CJK characters on the map. ([#5908](https://github.com/mapbox/mapbox-gl-native/pull/5908))
 * `-[MGLMapView resetPosition]` now resets to the current style’s default center coordinates, zoom level, direction, and pitch, if specified. ([#6127](https://github.com/mapbox/mapbox-gl-native/pull/6127))
 * Fixed an issue where feature querying sometimes failed to return the expected features when the map was tilted. ([#6773](https://github.com/mapbox/mapbox-gl-native/pull/6773))
 * MGLFeature’s `attributes` and `identifier` properties are now writable. ([#6728](https://github.com/mapbox/mapbox-gl-native/pull/6728))
 * The action sheet that appears when tapping the information button in the bottom-right corner now lists the correct attribution for the current style. ([#5999](https://github.com/mapbox/mapbox-gl-native/pull/5999))
-* The `text-pitch-alignment` property is now supported in stylesheets for improved street label legibility on a tilted map. ([#5288](https://github.com/mapbox/mapbox-gl-native/pull/5288))
-* The `icon-text-fit` and `icon-text-fit-padding` properties are now supported in stylesheets, allowing the background of a shield to automatically resize to fit the shield’s text. ([#5334](https://github.com/mapbox/mapbox-gl-native/pull/5334))
-* The `circle-pitch-scale` property is now supported in stylesheets, allowing circle features in a tilted base map to scale or remain the same size as the viewing distance changes. ([#5576](https://github.com/mapbox/mapbox-gl-native/pull/5576))
+* Added support for MGLSymbolStyleLayer’s `textPitchAlignment` property and the corresponding style JSON property for improved street label legibility on a tilted map. ([#5288](https://github.com/mapbox/mapbox-gl-native/pull/5288))
+* Added support for MGLSymbolStyleLayer’s `iconTextFit` and `iconTextFitPadding` properties and the corresponding style JSON properties, allowing the background of a shield to automatically resize to fit the shield’s text. ([#5334](https://github.com/mapbox/mapbox-gl-native/pull/5334))
+* Added support for MGLSymbolStyleLayer’s `circlePitchScale` property and the corresponding style JSON property, allowing circle features in a tilted base map to scale or remain the same size as the viewing distance changes. ([#5576](https://github.com/mapbox/mapbox-gl-native/pull/5576))
 * The `identifier` property of an MGLFeature may now be either a number or string. ([#5514](https://github.com/mapbox/mapbox-gl-native/pull/5514))
 * If MGLMapView is unable to obtain or parse a style, it now calls its delegate’s `-mapViewDidFailLoadingMap:withError:` method. ([#6145](https://github.com/mapbox/mapbox-gl-native/pull/6145))
 * Added the `-[MGLMapViewDelegate mapView:didFinishLoadingStyle:]` delegate method, which offers the earliest opportunity to modify the layout or appearance of the current style before the map view is displayed to the user. ([#6636](https://github.com/mapbox/mapbox-gl-native/pull/6636))
