chromeos: Create GBB at build time
The GBB contains hardware-specific data plus some configuration. The
latter isn't supported by this change yet and will come later.
The fields that are supported (hardware ID, bmpfv, vboot keys) are
configurable through Kconfig and point to Chrome OS-style default (eg.
developer keys).
While adding vboot keys, the two keys used to sign RW regions are also
added to Kconfig, even if not yet used.
