constify `Iterator`, take IV

Like its predecessors (rust-lang/rust#92433, rust-lang/rust#102225, rust-lang/rust#106541), this PR allows one to make `Iterator` implementations `const`, and thus enables the ability to have `for` loops in `const` contexts. I've also included constifying `Option as IntoIterator`, `option::IntoIter as Iterator` as a minimal dogfooding example.

But unlike its predecessors, it uses a new attribute (not unsound anymore!) that prevents any `Iterator` extension methods from being called. This is intentionally made minimal for an initial approval, the fun stuff like `.fold`, `Range as Iterator` could be done later.

cc @rust-lang/wg-const-eval, cc @oli-obk to review the compiler parts

Website | Getting started | Learn | Documentation | Contributing

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
