merge `DefKind::Coroutine` into `Defkind::Closure`

Related to #118188

We no longer need to be concerned about the precise type whether it's `DefKind::Closure` or `DefKind::Coroutine`.

Furthermore, thanks for the great work done by `@petrochenkov` on investigating https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/Why.20does.20it.20hang.20when.20querying.20.EF.BB.BF.60opt_def_kind.60.3F
