When a workflow is terminated or times out, dispatch cancel commands to workers for in-flight activities that registered a control queue. Extends the mechanism from #9233 to cover forceful workflow close scenarios (including reset, which terminates the old run). Guarded by EnableCancelActivityWorkerCommand. Disabled by default.

What
When a workflow is terminated or times out, dispatch cancel-commands to workers for in-flight activities. Extends the mechanism from #9233 to cover forceful workflow close scenarios (including reset, which terminates the old run).
Guarded by EnableCancelActivityWorkerCommand. Disabled.
Why
Previously, workers only discovered workflow termination/timeout passively via heartbeat (
NOT_FOUND) or when completing the activity. If heartbeat isn't enabled, activities run to completion uselessly.How did you test it?
