Fix intra-doc links for associated constants

Previously, only associated functions would be resolved. Fixes the issues in #75969 (comment).

I'm a little uncomfortable hard-coding the string constants, but it looks like that's how it's done elsewhere. I might make a follow-up PR at some point putting it in one place.

Not sure how to test associated types, since AFAIK there aren't any on primitives.
