Auto merge of #42854 - razielgn:relaxed-debug-constraints-on-maps-iterators, r=sfackler
Relaxed Debug constraints on {HashMap,BTreeMap}::{Keys,Values}. I has hit by this yesterday too. 😄 And I've realised that Debug for BTreeMap::{Keys,Values} wasn't formatting just keys and values respectively, but the whole map. 🤔 Fixed #41924 r? @jonhoo
