Previously, the HOB is defined, created and consumed only in StandaloneMmPkg. The HOB contains the number of processors and EFI_PROCESSOR_INFORMATION structure. This is the same as the information that PiSmmCpuDxeSmm uses EfiMpServiceProtocolGuid to get. The incoming plan is to create gMpInformationHobGuid for both StandaloneMm and legacy DXE_SMM in early phase. Then PiSmmCpuDxeSmm can consume the hob, which can simplified code logic about consuming MpService Protocol. So move this HOB definition to UefiCpuPkg.
