Separates logic from Chip. Chip is notch-aware.

Logic extracted from chip view into its own controller.
QuickStatusBarHeader is called when there are changes and sets the
visibility for the chip

Changed behavior when there is a top notch. When the chip is
visible and there's a notch the BatteryMeterView is set
to GONE.
