[PATCH v3 2/3] UefiPayloadPkg: Add PayloadLoaderPeim which can load ELF payload


Ni, Ray
 

Per universal payload spec, the payload is in ELF format.
The patch adds a payload loader that supports to load ELF image.

The location of extra data sections whose names start with "upld."
is stored in UNIVERSAL_PAYLOAD_EXTRA_DATA HOB.
