Hello build bot (Jenkins), Martin L Roth, Stefan Reinauer,

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. This is started via the ShimLayer,
which is added as the primary payload. The ShimLayer will build
the HOBs that Universal Payload requires and start it directly.

This is the reason that the Universal Payload is added to CBFS
as a raw file.

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 master, only when this patch is merged.

This is because the EDK2 engineers believe it is an impossible
task to patch coreboot to build and use Universal Payload.
