This commit is to add two new APIs in MdePkg PeiHobLib,
DxeHobLib, DxeCoreHobLib and MockHobLib:
1.The GetNextMemoryAllocationGuidHob () returns the next
instance of the Memory Allocation HOB with the matched
GUID from a starting HOB pointer.
2.The TagMemoryAllocationHobWithGuid () searchs the HOB
list for the Memory Allocation HOB with a matching base
address and set the Name GUID. Then the instance of the
tagged Memory Allocation HOB with matched base address is
returned.
