Implement Settings app UX for when a user has bluetooth config locked down.

When a user has the user restriction DISALLOW_CONFIG_BLUETOOTH
- Remove all the menu items for searching and other config
- Hide "available" but non-paired devices
- Remove settings button from paired devices
- Remove ability to make the device visible to others
