Reset requestedVisibleTypes after returning to window without editor focussed

The IME should not show after retuning to a window if there is no editor focussed, even if the requestedVisibleTypes for that window are set. Formerly, we only reset the requestedVisibleTypes for the IME, if it was shown and no editor focussed.
This CL passes the requested IME visibility when calling startInputOrWindowGainedFocus, so we can take that into account, whether the IME should be hidden.
