Re-Add WaitAllStoppedTimeout using WaitAllStopped, but deprecate it

Re-add `WaitAllStoppedTimeout()` to avoid breaking code using it, but deprecate it to signal that `WaitAllStopped()` should be used instead.

It is re-implemented via `WaitAllStopped()`; we can/will remove `WaitAllStoppedTimeout()` in the next major release
