protocol,types: Add secure & trusted boot state to system info

Add state of secure & trusted boot to struct system_info:

 - fw_measurement: whether the firmware has been measured
 - fw_enforcing: whether the firmware has been authenticated
 - os_enforcing: whether the boot payload will be authenticated
