Wow, there's three places that need this now?  :(

Robert, do you know if there's anything we can do to unify these?  It seems
pretty unfortunate to have to add keys in 3 separate places.  I'll never
remember them all on first try.  :)

Yeah, this is getting bad, especially as this is popping up in more places. We
unfortunately do need preregistration to ensure we have space enough for the
keys. In Crashpad we're looking at making this better via dynamic storage, but
it's quite tricky to do right in a potentially compromised context.

We may be able to move the registration list into a bare-bones target in
//components/crash, though…
