Add benchmarks and unit tests for GetSurfacePoints*. (#7216)

* Add benchmarks and unit tests for GetSurfacePoints*.
The benchmarks are very enlightening - the existing implementation of GetSurfacePointsFromRegion (and GetSurfacePointsFromList) is currently measurably *slower* than just calling GetSurfacePoints() many times in a loop.  This is due to all of the extra allocation overhead that's currently happening with the way these data structures are built.
