LibJS: Implement proper Iterator records

Instead of using plain objects as Iterator records, causes confusion
about the object itself actually being its [[Iterator]] slot, and
requires non-standard type conversion shenanigans fpr the [[NextValue]]
and [[Done]] internal slots,  implement a proper Iterator record struct
and use it throughout.

Also annotate the remaining Iterator AOs with spec comments while we're
here.
