By making RuntimeDeviceInformation class template independent, vtkm is able to detect device info at runtime with a runtime specified deviceId. In the past it's impossible because the CRTP pattern does not allow function overloading(compiler would complain that DeviceAdapterRuntimeDetector does not have Exists() function defined).
