  Log Message:
  -----------
  [libc++] Reimplement `optional<T&>` as a partial specialization (#201983)

- Break out the `optional<T&>` implementation that was interwoven with
the regular interface
- This should simplify the implementation
- And fix a missed added constraint for the `std::swap` specialization.
