Tommi 3c5450e693 Add support for PendingTaskSafetyFlag to ToQueuedTask.
This keeps usage of ToQueuedTask consistent and avoids callers having
to add additional boiler plate when using the safety flag.

From this:

tq->PostTask(ToQueuedTask([safety = my_safety_flag_]() {
  if (!safety->alive())
    return;
  Foo();
});

to this:

tq->PostTask(ToQueuedTask(my_safety_flag_, []() {
  Foo();
});
