This reverts commit 037ac99. As flaky CI failures have revealed, this feature was implemented incorrectly. `stop_sub_worker_contexts()` needs to be called on the thread on which the `Environment` is currently running, it’s not thread-safe. The current API requires `Stop()` to be thread-safe, though. We could add a new API for this, but unless there’s demand, that’s probably not necessary as `FreeEnvironment()` will also stop Workers, which is commonly the next action on an `Environment` instance after having `Stop()` called on it. Refs: nodejs#32531
This adds a regression test for terminating a Worker inside which another Worker is running.

I added this to v12.x-staging because people were reporting this bug occurring in v12.20.1, and it's a change that should definitely land everywhere where the original bug was also introduced. /cc @nodejs/lts |

Revert "embedding: make Stop() stop Workers"
This reverts commit 037ac99.
As flaky CI failures have revealed, this feature was implemented
incorrectly.
stop_sub_worker_contexts()needs to be called on thethread on which the
Environmentis currently running, it’s notthread-safe. The current API requires
Stop()to be thread-safe,though.
We could add a new API for this, but unless there’s demand, that’s
probably not necessary as
FreeEnvironment()will also stop Workers,which is commonly the next action on an
Environmentinstance afterhaving
Stop()called on it.Refs: #32531

This adds a regression test for terminating a Worker inside which
another Worker is running.
