Turbopack: reduce hmr chunk list subscriptions (#94062)
Previously, we created chunk list register chunks for every reachable
chunk in the chunk graph on a page. Now, we only create one that
subscribes to all recursively reachable assets.
This has to pass around an explicit list of client references chunks as
those cannot be discovered via the chunk graph alone.
This results in a significant performance improvement when loading pages
with the dev server, improving performance of a 60s cold build in a
large app by about 10s.
