Auto merge of #125775 - compiler-errors:uplift-closure-args, r=lcnr

Uplift `{Closure,Coroutine,CoroutineClosure}Args` and friends to `rustc_type_ir`

Part of converting the new solver's `structural_traits.rs` to be interner-agnostic.

I decided against aliasing `ClosureArgs<TyCtxt<'tcx>>` to `ClosureArgs<'tcx>` because it seemed so rare. I could do so if desired, though.
