MdeModulePkg PeiCore: Install SEC HOB data

Browse Source 
If the EFI_SEC_HOB_DATA_PPI is in the list of PPIs passed to the PEI
entry point, the PEI Foundation will call the GetHobs() member
function and install all HOBs returned into the HOB list. It does
this after installing all PPIs passed from SEC into the PPI database
and before dispatching any PEIMs.
