Add(copy) AdvancedConnectedDeviceDashboardFragment

AdvancedConnectedDeviceDashboardFragment is the same as
ConnectedDeviceDashboardFagment except for:
1. Bt preference is not MasterSwitchPreference anymore.
2. New Bluetooth file preference.

This cl copies following files:
1. connected_devices_advanced(from *_old)
2. Advanced*Fragment(from *Old)
3. Advanced*Test(from old test)

Future cl will work on differences.
