Old CPU models are not officially supported anymore by IBM, and for downstream builds of QEMU, we would like to be able to disable these CPUs in the build. Thus add a CONFIG switch that can be used to disable these CPUs (and old machine types that use them by default).

z13 is still supported so the patch needs to be fixed at least. Furthermore, z14 has the IBC/VAL cabability to behave like a z13, same for z15. (we do support VAL to N-2) I fail to see the value of this given how stable this code is.
