[DevTools] Build Updater List from the Commit instead of Map (#30897)

Stacked on #30896.

The problem with the `getUpdatersList` function is that it iterates over
Fibers and then looks up each of those Fibers in the
fiberToFiberInstanceMap which we ideally could get rid of.

However, every time an updater comes into play for a commit it must mean
that something below the updater itself updated and so the updater will
also be cloned which means we'll pass it on the way down when traversing
the tree in the commit.

When we do this traversal, we can just look if the Fiber is in the
updater set and if so add it to the updater list as we go.
