vm: properly handle defining symbol props

This PR is a follow-up of #46615.

When bumping V8 for node 18, various bugs appeared around vm.
Some have been fixed along the flow, but there is at least one
remaining and described at:
jestjs/jest#13338.

The current fix does nothing on node 20: the new bump of v8 done for
node 20 seems to fix it. But it would fix the problem in both node 18
and node 19. I confirmed it would fix node 19 by cherry-picking the
commit on v19.x-staging and launching `make -j4 jstest` on it.
