Add layout for advanced BT detail header

If device supports metadata, then we display advanced UI in Bluetooth
details header. This CL adds layout for this header.

In advanced layout, it will show:
1. Device name
2. Left, right and case icon
3. Left, right and case battery level

Once API is ready, following CL will get metadata from it and set it
to UI.
