[wm] Drop no focused window ANR request if the activity is stopped

If the activity is in stopped state it will not have a visible
window on screen. In this case drop any ANR request which tries to
blame the app if it's focused without a window. This can happen on
some products which do not have a focused system window when the
display is turned off.

Test: turn of display, send keyevent
