LUCENE-6544: Geo3D: Regularize path & polygon construction, add 
PlanetModel.surfaceDistance(), cache lat & lon in GeoPoint, add thread-safety 
where missing -- Geo3dShape.

> Geo3d cleanup: Regularize path and polygon construction, plus consider adding 
> ellipsoid surface distance method

> Geo3d's way of constructing polygons and paths differs in that in one case 
> you construct points and the other you feed lat/lon values directly to the 
> builder.  Probably both should be supported for both kinds of entity.
> Also it may be useful to have an accurate point-point ellipsoidal distance 
> function.  This is expensive and would be an addition to the arc distance we 
> currently compute.  It would probably be called "surface distance".
