Auto merge of #123531 - compiler-errors:closure-wf, r=oli-obk
Enforce closure args + return type are WF
I found this out when investigating https://github.com/rust-lang/rust/issues/123461#issuecomment-2040894359. Turns out we don't register WF obligations for closure args and return types, leading to the ICE.
~~I think this is a useful thing to check for, but I'd like to check what the fallout is.~~ crater is complete.
~~Worst case, I think we should enforce this across an edition boundary (and possibly eventually migrate this for all editions) -- this should be super easy to do, since this is a check in HIR wfcheck, so it can be made edition dependent.~~ I believe the regressions are manageable enough to not necessitate edition-specific behavior.
Fixes #123461
