x86/sev: Provide support for SNP guest request NAEs
Version 2 of GHCB specification provides SNP_GUEST_REQUEST and
SNP_EXT_GUEST_REQUEST NAE that can be used by the SNP guest to
communicate with the PSP.
While at it, add a snp_issue_guest_request() helper that will be used by
driver or other subsystem to issue the request to PSP.
See SEV-SNP firmware and GHCB spec for more details.
