To support Secure TSC, SNP guest messages need to be used during the early boot.
Most of the guest messaging code is currently part of sev-guest driver
and header. I have opportunistically moved the header in this patch as I was adding
guest request structure. Movement of rest of the functions implementation
from sev-guest.c => kernel/sev.c is done in patch 7/16.

As per https://lore.kernel.org/all/Yg5nh1RknPRwIrb8@xxxxxxx/, I can move the snp
guest messaging code implementation to arch/x86/coco/sev/guest-msg.[ch]
