Reduce unnecessary calculation from input device change
The notifyConfigurationChanged can be called for any attributes
change of InputDevice. And the change may be unrelated to display
configuration. E.g. motion range change of touch panel.
So before asking window manager to recompute entire display
configuration, check if attributes which can affect display are
changed. That reduces the execution time of the method from
5ms to <0.1ms when turning on/off screen, and it reduces lock
contention between other important operations.
