Embedded	HOB list GUID, split across two QWORD-aligned storage locations
for	efficient comparison in CompareGuidPair().
gHobListGuid	= {7739F24C-93D7-11D4-9A3A-0090273FC14D}
Stored	as two UINT64 values at gHobListGuidLo (0xB40) and
gHobListGuidHi	(0xB48) for the inline comparison function to access
without	loading the full GUID from .rdata.

Walk	the configuration table looking for the HOB list GUID.
Each	entry is an EFI_CONFIGURATION_TULE (16-byte GUID + pointer).

VendorTable	follows the GUID in the configuration table entry.
