The register specifications have been taken as a superset of the coreboot
documentation as different flags were documented in more detail on various
different platforms.
Having this new data allows us to add future tests and make the current tests
much easier to understand.
To do this, rely on the AppStream ID to map to a translated string (providing a
fallback for clients that do not care) and switch the free-form result string
into a set of enumerated values that can be translated.
This fixes some of the problems where some things have to be enabled to "pass"
and other attributes have to be some other state. For cases where we want the
user to "do" something, provide a URL to a wiki page that we update out-of-band
of fwupd releases.
