Rollup merge of #88789 - the8472:rm-zip-bound, r=JohnTitor
remove unnecessary bound on Zip specialization impl I originally added this bound in an attempt to make the specialization sound for owning iterators but it was never correct here and the correct and [already implemented](https://github.com/rust-lang/rust/blob/497ee321af3b8496eaccd7af7b437f18bab81abf/library/alloc/src/vec/into_iter.rs#L220-L232) solution is is to place it on the IntoIter implementation.
