Summary: This patch adds the `<experimental/utility>` header as specified in the latest draft of the library fundamentals TS. `<experimental/utility>` only contains `class erased_type`. This patch also updates the documentation to list the `erased_type` class as "initial implementation complete". Test Plan: Three test cases where added: 1. Test that `_LIBCPP_VERSION` is defined. 2. Test that `<utility>` has been included. 3. Test that `erased_type` is in the correct namespace and is constexpr default constructible.
