IVGCVSW-6119 ConstTensorsAsInput: FullyConnected Bug Fix

 * Updated FullyConnected layer member variables when cloning as
   some backends still require them.
 * Added SetConstant call when using deprecated AddFullyConnectedLayer
   method to ensure backwards compatibility.
 * Added SetConstant to SimpleSample to ensure it runs on all backends.
