debug format `Const`'s less verbosely
Not user visible change only visible to people debugging const generics.
Currently debug output for `ty::Const` is super verbose (even for `-Zverbose` lol), things like printing infer vars as `Infer(Var(?0c))` instead of just `?0c`, bound vars and placeholders not using `^0_1` or `!0_1` syntax respectively. With these changes its imo better but not perfect:
`Const { ty: usize, kind: ^0_1 }`
is still a lot for not much information. not entirely sure what to do about that so not dealing with it yet.
Need to do formatting for `ConstKind::Expr` at some point too since rn it sucks (doesn't even print anything with `Display`) not gonna do that in this PR either.
