Add guest api and guest kernel support for SEV live migration. Introduces a new hypercall to notify the host of changes to the page encryption status. If the page is encrypted then it must be migrated through the SEV firmware or a helper VM sharing the key. If page is not encrypted then it can be migrated normally by userspace. This new hypercall is invoked using paravirt_ops. Conflicts: sev_active() replaced by cc_platform_has(CC_ATTR_GUEST_MEM_ENCRYPT).
