UefiCpuPkg/SecCore: Re-install SEC platform information(2) PPI

Browse Source 
In SecTemporaryRamDone(), we will build one privated GUIDed-HOB to save CPU BIST
Data and re-install SEC platform information(2) PPI. Then other PEI drivers
could get CPU BIST data from the private GUIDed-HOB by new installed PPI.
