cpu: Introduce CPU model deprecation API
Implement the ability of marking some versions deprecated. When
that CPU model is chosen, print a warning. The warning message
can be customized, e.g. suggesting an alternative CPU model to be
used instead.
The deprecation message will be printed by x86_cpu_list_entry(),
e.g. '-cpu help'.
QMP command 'query-cpu-definitions' will return a bool value
indicating the deprecation status.
