Prototype to use details or settings panels

Adds a device config flag to change behavior of tile press or long
press:
adb shell device_config put systemui qs_use_settings_panel <X>

0 - default
1 - use panels on long press
2 - use panels on click
3 - use old details

Currently, there's only a Wifi panel.
Also, enabling details makes it so long press on collapsed QS does
nothing.

Test: manual
