Passing Ime statsToken from InputMethodManager to InsetsController

Calls from InputMethodManager are in general redirected to InsetsController. In case of InputMethodManager#hideSoftInputFromWindow and InputMethodManager.DelegateImpl#onWindowLostFocus, we didn't pass the statsToken. Thus, the request was only tracked from InsetsController. To have the right origin, we pass the statsToken now.

Test: None, logs only
