Zhiguang Liu 82f727c4af UefiPayloadPkg: Add HobLib for UniversalPayload
For payload entry, use PayloadEntryHobLib as HobLib and payload entry
should initialize hob base.
For DxeCore, use new added DxeHobLib as HobLib, and DxeCore will
initialize hob base.
For Dxe Driver, use new added DxeHobLib as HobLib, and use DxeHobListLib
to initialize hob base.

Adding a new library DxeHobLib + DxeHobListLib instead of using the
DxeHobLib.inf in MdePkg is because the constructor needed be separated
from DxeHobLib.
If not, when building UefiPayloadPkg, the dependency chain is as below:
DebugLib -> SerialPortLib -> PlatformHookLib -> HobLib -> DebugLib
Each library has a constructor, and this becomes a constructor circle.
To break the circle, separate the constructor from the HobLib as a new
DxeHobListLib, which won't depend on DebugLib.
