Add support for "-cpu max" for ARM guests. This CPU type behaves like "-cpu host" when KVM is enabled, and like a system CPU with the maximum possible feature set otherwise. (Note that this means it won't be migratable across versions, as we will likely add features to it in future.) Backports commit bab52d4bba3f22921a690a887b4bd0342f2754cd from qemu
