Chris Tate 05f2dd5859 Walk Map and Set iterators inside iterator helper objects ...

A helper object over a Map or Set iterator that is stored and consumed
later (const it = set.values().map(f); for (const x of it) ...) stepped
the runtime's checked iterator through an adapter generator, boxing each
value and resuming two generators per element: 5.1x Node's time on a
100k-element Set.

A stage on m.keys(), m.values(), m.entries() (or a Set's), or on
Iterator.from(set) or Iterator.from(map), now walks the collection inside
the helper's own generator. The walk steps the runtime's native iterator
by entry index through the new scr_dyn_collection_iterator_index and
reads each key or value with the typed intrinsics. The native iterator
keeps the walk live and ends the collection's iteration when it is
exhausted or released, so an abandoned or returned helper leaves the
collection free to compact. Other helper sources over a Map or Set, and
Iterator.from over a Set or Map, use a typed generator over the
collection built the same way.
