machine: Add a valid_cpu_types property
This patch add a MachineClass element that can be set in the machine C
code to specify a list of supported CPU types. If the supported CPU
types are specified the user enter CPU (by -cpu at runtime) is checked
against the supported types and QEMU exits if they aren't supported.
