cbmem_console: Document known reimpementations of console structure/API
It turns out that there are quite a few other projects that can access
the CBMEM console by now. If we ever want to make another structural or
behavioral change to it, we need to know where these implementations are
so we can make sure they're all getting updated. Let's try to build a
comprehensive list in the file that should be the source of truth for
all (coreboot's own implementation).
