Note that libgeometry is already included in `filament-android`, this simply exposes more of its existing functionality. The Java version of SurfaceOrientation is similar to the JavaScript version because we are bundling it into the main Filament package, even though it is a separate library in C++. This is much simpler than creating a brand new Java package. New Android sample that tests this is forthcoming. Fixes #1729.
