Class_PIEnable[0]: Update PeiServicesLib based on new features defined in PI spec.
Code Change :
1) Add the following services:PeiServicesRegisterForShadow, PeiServicesFfsGetFileInfo, PeiServicesFfsFindFileByName and PeiServicesFfsGetVolumeInfo
2) The paramter list of these functiuon has also been updated to replace EFI_FIRMWARE_VOLUME_HEADER to EFI_PEI_FV_HANDLE and EFI_FFS_FILE_HEADER
to EFI_PEI_FILE_HANDLE.
3) Add CONST to parameter of PeiServices EFI_PEI_SERVICES.EFI_PEI_RESET_SYSTEM
Possible Impacts:
1) Platform code should be updated to make use of these new PI features. The functions in MdePkg/Include/Library/PeiServicesLib.h are
recommended as PeiServices is saved for every PEI Services API invokation.
2) Now PEIM entry point is upadted to pass in PeiServices in type of (CONST EFI_PEI_SERVICS **). Platform code should be updated to
add (EFI_PEI_SERVICS **) cast to PeiServices before passing it to the previously defined PPI interface which needs a (EFI_PEI_SERVICS **)
type for PeiServices parameter.
3) The newly defined PPI should not inlcude PeiSevices in the paramter list as PI spec has standard way to retrive PeiServices (check VOL 1
Section 4.4 PEI Sevices Table Retrieval) for details. Beside, GetPeiServicesTablePointer() in MdePkg\Include\Library\PeiServicesTablePointerLib.h
also provide convinient way to retrieve the pointer to Pei Service Table.
