There are comments that FIT is Intel specific specification instead of industry standard, which should not be placed in EDK2 MdePkg and UefiCpuPkg. So this patch adds a platform PPI for the microcode shadow logic, and remove the FIT related code from EDK2. The FIT based microcode shadow support will be implemented as a new platform PEIM in IntelSiliconPkg in edk2-platforms. This patch doesn't provide a DXE version shadow microcode protocol, a platform which only uses DxeMpInitLib instance only supports PCD based microcode shadowing.
