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.
