[ios, osx] Ignore compound shape types as annotations

Ignore any multipolyline, multipolygon, or shape collection object passed into -addAnnotation: or -addAnnotations:. Previously, these methods broke apart the compound shape into its constituent shapes in order to recursively add them to the map. But that broke assumptions about a one-to-one correspondence between annotations and their contexts during selection and deletion.
