IVGCVSW-6127 ConstTensorsAsInput: DepthwiseConvolution2d

!android-nn-driver:7418

 * Update Front-end and Tools.
 * Updated Serializer, Deserializer and unit tests to reflect this.
 * Updated TfLiteDelegate, TfLiteParser and OnnxParser.
 * Change NNDriver to new API.
 * Updated Ref.
 * Neon and Cl backend partially completed (Backend.cpp files).
 * Added dynamic or constant input EndToEnd tests.
 * Added ConstantTensorAsInputMemeberVariableRedirect Optimization.
