Profile Max Used Heap size at runtime 

This records the maximum usage of heap at runtime. The Stage1/2 heap
sometimes reaches OUT OF RESOURCE even if it looks there is enough
usable space in the heap. This is because AllocateTemporaryMemory()
sometime exceeds the heap boundary. ex) IppCryptoLib
This would help identify proper heap size required in each stages.
