Resolve `$crate`s for pretty-printing at more appropriate time

Doing it in `BuildReducedGraphVisitor` wasn't a good idea, identifiers wasn't actually visited half of the time.
As a result some `$crate`s weren't resolved and were therefore pretty-printed as `$crate` literally, which turns into two tokens during re-parsing of the pretty-printed text.

Now we are visiting and resolving `$crate` identifiers in an item right before sending that item to a proc macro attribute or derive.

Fixes https://github.com/rust-lang/rust/issues/57089
