Add missing sensor types to <android/sensor.h>.

This matches

I've included the types for a few of the easy cases, but I've added a
link to the Java documentation for the rest: the Java documentation is
much better and actively maintained. Duplicating it here doesn't seem
worthwhile, and <android/multinetwork.h> already takes this approach.
