[ios, macos] Hook up hillshade style layers, raster DEM sources to iOS/macOS (#11036)

* [ios, macos] Finished implementing MGLHillshadeStyleLayer

* [macos] Added icon for hillshade layer

Also set the background layer icon to mirror in right-to-left locales.

* [ios, macos] Implemented raster DEM source

* [macos] Added Enhance Terrain debugging command

* [ios, macos] Simplified raster DEM source example
