Yes, there isn't a convenient way of doing so in the diagnostics engine
unfortunately. I'd love for us to have that! But typically we just define it
elsewhere. For large lists like this it can make it significantly more
readable, and much less likely to not be updated because of a copy/paste error
(which happens OFTEN).
See `AttributeArgumentNType` and `AttributeDeclKind` for some examples, but
they are kind of sprinkled in quite a few places, Richard had me do some a few
times IIRC for function multiversioning. `Sema::checkTargetVersionAttr` has
some more local versions of it.
