This	module is a UEFI Shell-based System Inventory Diagnostic Tool.
It	locates the gSystemInventoryProtocol (or gBmcSystemInventoryProtocol)
and	dumps inventory data for CPU, DIMM, PCIe, and HDD subsystems.

inventory	protocol, and dumps inventory data for the requested
subsystem	(cpu/dimm/pci/hdd).
Behavior	modes (based on Argc/Argv):
Save	global protocol pointers
Initialize	HOB list
Initialize	cached system table copies
Try	alternate protocol
argc	*OffsetsTable = Argv; // argv**
Show	struct layout info only
Check	for "debug" keyword	show full struct layout
