impl `Default` for `HashMap`/`HashSet` iterators that don't already have it This is a follow-up to #128261 that isn't included in that PR because it depends on: * [x] rust-lang/hashbrown#542 (`Default`) * [x] `hashbrown` release containing above It also wasn't included in #128261 initially and should have its own FCP, since these are also insta-stable. Changes added: * `Default for hash_map::{Iter, IterMut, IntoIter, IntoKeys, IntoValues, Keys, Values, ValuesMut}` * `Default for hash_set::{Iter, IntoIter}` Changes that were added before FCP, but are being deferred to later: * `Clone for hash_map::{IntoIter, IntoKeys, IntoValues} where K: Clone, V: Clone` * `Clone for hash_set::IntoIter where K: Clone`
