sev/i386: add support to LAUNCH_MEASURE command
During machine creation we encrypted the guest bios image, the LAUNCH_MEASURE command can be used to retrieve the measurement of the encrypted memory region. This measurement is a signature of the memory contents that can be sent to the guest owner as an attestation that the memory was encrypted correctly by the firmware. VM management tools like libvirt can query the measurement using query-sev-launch-measure QMP command.
