9f471fd1 - [libc++][hardening] Constrain construction for `__{(static_)bounded,wrap}_iter` (#115271)

[libc++][hardening] Constrain construction for `__{(static_)bounded,wrap}_iter` (#115271) This PR restricts construction to cases where reference types of source/destination iterators are (`T&`, `T&`) or (`T&`, `const T&`) ( where `T` can be const). Fixes #50058.
