UefiCpuPkg: Update AddressEncMask in CpuPageTable
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
MMIO region in Tdx guest is set with PcdTdxSharedBitMask in TdxDxe's
entry point. In SEV guest the page table entries is set with
PcdPteMemoryEncryptionAddressOrMask when creating 1:1 identity table.
So the AddressEncMask in GetPageTableEntry (@CpuPageTable.c) is either
PcdPteMemoryEncryptionAddressOrMask (in SEV guest), or
PcdTdxSharedBitMask (in TDX guest), or all-0 (in Legacy guest).
