Soong's multi-architecture building has grown complex, with the combination of HostOrDevice+HostType+Arch necessary to determine how to build a variant of a module, and three separate mutators to split each into its variations. Combine HostOrDevice+HostType into Os, which will be Linux, Darwin, Windows, or Android. Store Os+Arch as a single Target. Change-Id: Iae677eff61a851b65a7192a47f2dc17c1abb4160
