Common shade width across devices.

Use 400dp as the visual width of the shade across all devices
and orientations, except small device portrait.

Since the width is now dynamic across orientations, update the
necessary views in SystemUI on rotate.

Remove obsolete styles + resources.

Set max QS columns to 3 on all devices, due to the newer shade
width.
