payloads/external: add support for BOOTBOOT payload

Browse Source 
BOOTBOOT is a multi-platform, architecture agnostic boot protocol.
The protocol describes how to boot an ELF64 or PE32+ executable inside
an initial ram disk image into clean 64 bit mode. This version uses
libpayload to do that. Depending on the lib's configuration, initrd
can be in ROM as a cbfs file or a Flashmap partition; on disk a GPT
partition or a file on a FAT formatted ESP partition.
