x86/sev: Introduce an SNP leaked pages list
Pages are unsafe to be released back to the page-allocator if they
have been transitioned to firmware/guest state and can't be reclaimed
or transitioned back to hypervisor/shared state. In this case, add them
to an internal leaked pages list to ensure that they are not freed or
touched/accessed to cause fatal page faults.
