Add initial draft for a EFI Android Boot protocol

We are starting to interact more with vendor firmwares and will soon
need an interface to handle platform specific operations needed to
implement GBL features. Starts an initial draft for adding EFI protocol
interfaces that can be used by EFI applications to implement android
verified booting, fastboot etc. Initially added abstracted interfaces
for Fastboot over USB.

The draft will be used as a basis for development and iteration and
will continously evolve.
