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.

/** @file
Provides a service to retrieve a pointer to the start of HOB list.
Only available to DXE module types.
This library does not contain any functions or macros. It simply exports a global
pointer to the start of HOB list as defined in the Platform Initialization Driver
Execution Environment Core Interface Specification. The library constructor must
initialize this global pointer to the start of HOB list, so it is available at the
module's entry point. Since there is overhead in looking up the pointer to the start
of HOB list, only those modules that actually require access to the HOB list
should use this library.
