x86/cpufeatures: Add SNP Secure TSC
The Secure TSC feature for SEV-SNP allows guests to securely use the RDTSC
and RDTSCP instructions, ensuring that the parameters used cannot be
altered by the hypervisor once the guest is launched. For more details,
refer to the AMD64 APM Vol 2, Section "Secure TSC".
