Original change's description:
> bluetooth: add BluetoothAdapter::IsPeripheralRoleSupported()
> 
> It appears that on Windows, Bluetooth hardware does not generally
> support the BLE peripheral role (i.e. BLE advertisements). Add a method
> to BluetoothAdapter that returns the
> BluetoothAdapter.IsPeripheralRoleSupported property [0] on WinRT and
> true everywhere else, so that client code can detect these cases.
