IVGCVSW-6119 ConstTensorsAsInput: FullyConnected

 * Constant weights and biases are now stored as Constant layers.
 * Updated Serializer, Deserializer and unit tests to reflect this.
 * Updated TfLiteDelegate, TfLiteParser and OnnxParser.
 * Updated Schema with IsConstant and ConstantTensorsAsInputs.
 * Updated Ref backend to handle constant weights and
   bias as inputs rather than reading from member variables.
 * Added dynamic or constant input EndToEnd tests.
