Change ty and const error's pretty printing to be in braces
`[const error]` and `[type error]` are slightly confusing since they look like either a slice with an error type for the element ty or a slice with a const argument as the type ???. This PR changes them to display as `{const error}` and `{type error}` similar to `{integer}`.
This does not update the `Debug` impls for them which is done in rust-lang#111988.
I updated some error logic to avoid printing the substs of trait refs when unable to resolve an assoc item for them, this avoids emitting errors with `{type error}` in them. The substs are not relevant for these errors since we don't take into account the substs when resolving the assoc item.

TyKind: Debugimpl is basically unusable for debugging, its too verbose even for verbose debugging 🤣 This PR replaces the debug logic forTyKindwith a more manual debug impl instead of a hand expanded derived impl. This should help make #107084 more reasonable to land since the output ofTy: Debugwill be better.This isn't a fully completed change to the
Debugimpl ofTyKindas there's still logic from the derive macro for some variants. Some of the variants are also not consisten with the-Zverboseprinting ofTy, ideally-Zverboseprinting ofTywould also just defer to the debug impl instead of having lots of checks in pretty printing. I plan on fixing this in follow up PRs since it seems tricky to do in this one and its already a large PR 😅
