Lendacky, Thomas cc71bd9709 OvmfPkg/VmgExitLib: Add support for new MMIO MOV opcodes 
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3345

Enabling TPM support results in guest termination of an SEV-ES guest
because it uses MMIO opcodes that are not currently supported.

Add support for the new MMIO opcodes (0xA0 - 0xA3), MOV instructions which
use a memory offset directly encoded in the instruction. Also, add a DEBUG
statement to identify an unsupported MMIO opcode being used.
