This patch adds a new line to `cbfstool print -v` output that records
the overall CBFS verification health of the image. While this info was
already visible from individual fields before, it's nice to have a
one-stop location to see "this is a good image" without having to
carefully parse a lot of output manually.
Also add a few lines to the Makefile that check whether this field is
valid for the final image (it always should be, but hopefully this check
will allow us to catch regressions like the one fixed by CB:64547 sooner
in the future).

This patch contains several minor cleanups related to compiler.h:
- Replace __always_unused() (which is a Linux-specific concept that
doesn't make sense without also having __maybe_unused(), and had zero
uses in the codebase) with __unused() which moves here from helpers.h
- Add __underscores__ to the names of all attributes in the compiler
attribute shorthand macros. This is necessary to make them work in
files where the same name was already used for an identifier (e.g.
cbfstool/cbfs.h's `unused` array of file types).
- Remove libpayload's own copy of compiler.h and make it directly pull
in the commonlib/bsd copy.
