UefiCpuPkg/CpuDxe: Add support for PCD PcdPteMemoryEncryptionAddressOrMask
This PCD holds the address mask for page table entries when memory
encryption is enabled on AMD processors supporting the Secure Encrypted
Virtualization (SEV) feature.
The mask is applied when page tables entries are created or modified.
