SystemUI: open settings panel if there are no notifications

If there are no notifications that belong to the current user, then automatically open the quick settings menu (like the two-finger open). It only ignores the ADB icon for now (which is pretty useless) but could be extended to ignore the usb mounting one or maybe another?

TODO: add Settings.System toggle to disable the option

This is always enabled with a fixed 80% width trigger.
