MVP fix for a worker_threads crash where ~WorkerThreadData() -> ~IsolateData() -> Isolate::DetachCppHeap() kicks off a round of garbage collection that expects an entered isolate. No test because the crash is not reliably reproducable but the bug is pretty clearly described in the linked issue and is obvious once you see it, IMO. Fixes: nodejs#51129

By the way it just occurred to me - consider this non-blocking - why can we not just do this directly in the IsolateData destructor instead? That would correct this for the embedder-facing |

I considered that but I'm not 100% sure it won't cause deadlocks. |
