i386: Make unversioned CPU models be aliases
This will make unversioned CPU models behavior depend on the machine type: * "pc-*-4.0" and older will not report them as aliases. This is done to keep compatibility with older QEMU versions after management software starts translating aliases. * "pc-*-4.1" will translate unversioned CPU models to -v1. This is done to keep compatibility with existing management software, that still relies on CPU model runnability promises. * "none" will translate unversioned CPU models to their latest version. This is planned become the default in future machine types (probably in pc-*-4.3).
