thermal: Add initial VIRTUAL-SKIN-OUTER-DISPLAY

To monitor and verify the feature of "sensor name based brightness
throttling", add VIRTUAL-SKIN-OUTER-DISPLAY of type DISPLAY.

But to ensure no regression, set its equation to be same as VIRTUAL-SKIN
and in future once verified we can update the equation.
