payloads/edk2: Add an option to use EDK2 Universal Payload
This add's an option to use EDK2's Universal Payload instead
of the standard UefiPayloadPkg. Universal Payload requires
a ShimLayer, to build the required HOBs and pass them to Universal
Payload.
The ShimLayer is built to encompass UniveralPayload, so only
one ELF binary is added to coreboot.
Universal Payload is based on Intel's USF specification:
https://universalscalablefirmware.github.io/documentation/
This has been added with the repository pointing to
https://github.com/starlabsltd. The required ShimLayer patches
will be merged into edk2 master once corresponding coreboot
patches are merged.
This is because the EDK2 engineers believe it is an impossible
task to patch coreboot to build and use Universal Payload.
