/**
This function for GetMemoryMap() with properties table capability.
It calls original GetMemoryMap() to get the original memory map information. Then
plus the additional memory map entries for PE Code/Data seperation.
@param MemoryMapSize A pointer to the size, in bytes, of the
MemoryMap buffer. On input, this is the size of
the buffer allocated by the caller. On output,
it is the size of the buffer returned by the
firmware if the buffer was large enough, or the
size of the buffer needed to contain the map if
the buffer was too small.
@param MemoryMap A pointer to the buffer in which firmware places
the current memory map.
@param MapKey A pointer to the location in which firmware
returns the key for the current memory map.
@param DescriptorSize A pointer to the location in which firmware
returns the size, in bytes, of an individual
EFI_MEMORY_DESCRIPTOR.
@param DescriptorVersion A pointer to the location in which firmware
returns the version number associated with the
EFI_MEMORY_DESCRIPTOR.
@retval EFI_SUCCESS The memory map was returned in the MemoryMap
buffer.
@retval EFI_BUFFER_TOO_SMALL The MemoryMap buffer was too small. The current
buffer size needed to hold the memory map is
returned in MemoryMapSize.
@retval EFI_INVALID_PARAMETER One of the parameters has an invalid value.
