The previous TDX MmioExit doesn't handle the Mmio instructions correctly in some scenarios. This patch-set refactors the implementation to fix the issues. Before the refactoring, common X86 instruction codes in CcExitVcHandler.c are moved to separate files (CcInstruction.h / CcInstruction.c) so that these codes can be re-used in TDX.
