MdeModulePkg/UniversalPayload: Add definition for extra info in payload
The payload is in ELF format per the universal payload spec.
UNIVERSAL_PAYLOAD_INFO_HEADER is stored in the ELF payload as a separate
section named ".upld_info".
Extra data needed by payload is stored in sections whose name starts
with ".upld.".
