Original change's description:
> Define basic Trichrome build targets.
> 
> This defines basic build targets for a Trichrome build using the
> upstream package names/configuration. The shared library APK contains
> the 32-bit version of libmonochrome.so and a few autogenerated Java
> pieces only at this stage, which means the total size of the three APKs
> is significantly larger than Monochrome at present.
