Tie KeyguardStateCallbackInteractor state to WmLockscreenVisibility + add dismiss callback notifications.

Using KTF state resulted in some showing-state updates coming in just before the WM setLockScreenShown call, which causes issues in tests and also logically doesn't make sense.

Also, whenever we setLockScreenShown(false), notify the dismiss callback registry.
