Complement versioned CPU model framework with the ability of marking some
versions deprecated. When that CPU model is chosen, get some warning. The
warning message is customized, e.g. telling in which future QEMU version will
it be obsoleted.
The deprecation message will also appear by x86_cpu_list_entry(), e.g. '-cpu
help'.
QMP 'query-cpu-definitions' will also return a bool value indicating the
deprecation status.
