BluetoothDevice::IsPaired() returns whether or not the machine is physically
paired with the bt device. But we want to show if the website is paired with the
device. A website is paired with a device if it's in WebBluetoothServiceImpl's
allowed_devices_map_.

You could pass in a reference to the map of allowed devices and query it here.
You will probably have to pass in the origin as well.
