Also fixes "Large text" option on lockscreen and fixes Keyguard
layout on smaller devies. In addition, make sure that landscape
layout for phones isn't terrible broken (it's not pretty but
it works).

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.

Make existing QS panel available via pulldown from header
(or keyguard status view on keyguard), update the affordances
as a hint.
Don't allow QS to scroll, cap to max rows.
Add scrim over panel to indicate that this is purely temporary.
