Subject: [edk2] [PATCH v3 4/5] MdeModulePkg/DxeCorePerformanceLib: use AllocatePeiAccessiblePages

Replace the call to and implementation of the function
FpdtAllocateReservedMemoryBelow4G() with a call to AllocatePeiAccessiblePages, which boils down to the same on X64, but does not crash non-X64 systems that lack memory below 4 GB.
