MdeModulePkg MemoryProfile.h:two bytes of Reserved[4] as ActionStringOffset 

At 94092aa603, we extended
MEMORY_PROFILE_ALLOC_INFO to add ActionStringOffset and
Reserved2[6] fields, that was not aware the Reserved[4]
field can be reused to have better memory profile database
size efficiency.

With the patch, PcdMemoryProfilePropertyMask|0x3 and
PcdMemoryProfileMemoryType|0xffff, the memory profile
database size can be reduced as below on my sample platform.

UefiMemoryProfileSize - 0x1597A8 -> UefiMemoryProfileSize - 0x12AB28
SmramProfileSize - 0xCF68 -> SmramProfileSize - 0xB8E8
