This PR moves many constants of the iterator API from `Std.Iterators` to the `Std` namespace in order to make them more convenient to use. These constants include, but are not limited to, `Iter`, `IterM` and `IteratorLoop`. This is a breaking change. If something breaks, try adding `open Std` in order to make these constants available again. If some constants in the `Std.Iterators` namespace cannot be found, they can be found directly in `Std` now.
