Replaces the `for await (const _ of source) {}` discard idiom with
dump(), which says what it does and does not need an eslint-disable
for the unused loop variable. The eslint-disable directives and
comments that become redundant are removed with it.
Only files that already declare --experimental-stream-iter are
converted, so no test gains an experimental flag it did not already
opt into. Files still using the old idiom are left as they are;
converting them would change what those tests run under and belongs
in a separate discussion.
Loops that break early are left alone: those cancel the source rather
than reading it to completion, which is not what dump() does.
