[edk2-devel] [PATCH V2 1/3] MdePkg: Add Tdx support lib

Intel Trust Domain Extension (Intel TDX) refers to an Intel technology
that extends Virtual Machines Extensions (VMX) and Multi-Key Total
Memory Encryption (MKTME) with a new kind of virtual machine guest
called a Trust Domain (TD).
TdxLib is created with functions to perform the related Tdx operation.
This includes functions for:
- TdCall : to cause a VM exit to the Intel TDX module
- TdVmCall : it is a leaf function 0 for TDCALL
- TdVmCallCpuid : enable the TD guest to request VMM to emulate CPUID
- TdReport : to retrieve TDREPORT_STRUCT
- TdAcceptPages : to accept pending private pages
- TdExtendRtmr : to extend one of the RTMR registers
The base function in this dirver will not do anything and will return
an error if a return value is required. It is expected that other
packages (like OvmfPkg) will create a version of the library to fully
support a TD guest.
