MdeModulePkg: Allow DxeIpl to load without permanent memory

Browse Source 
PI1.4a spec added "For S3 resume boot modes DXE IPL must be
prepared to execute without permanent memory installed and
invoke the S3 resume modules."

To follow PI1.4a spec, this patch is to update DxeIpl and
PeiCore to enable S3 resume from temporary memory.
The normal boot path still enforces the permanent memory
requirement.
