Utilize Measured Energy data in PowerStatsViewer

Browse Source 
Display measured energy adjusted screen power alongside the currently
reported screen power. Also report measured ambient display power to the
Ambient display drain.

Test: manual ("mp :PowerStatsViewer", will show adjusted screen power on PowerStatsHal2.0 enabled devices with display rails)
