qapi, target/i386/sev: Add cpu0-id to query-sev-capabilities
Add a new field 'cpu0-id' to the response of query-sev-capabilities QMP
command. The value of the field is the base64-encoded unique ID of CPU0
(socket 0), which can be used to retrieve the signed CEK of the CPU from
AMD's Key Distribution Service (KDS).
