[ios] Summarize places, roads after zooming with VoiceOver

After zooming, MGLMapView’s accessibility value now indicates the number of visible roads and lists out a few places visible in the current viewport, starting with the features at the highest z-index (not necessarily the largest or the closest to the center of the view). Avoid saying that no annotations are visible.
