[ Property ] Add Tensor Type property in model

This PR enables the tensor type in model property as
"tensor_type=NHWC" or "tensor_type=NCHW". This information goes to
network_grap and layer node & manager.

Then, each layer can get the model tensor type information and it can
be used to request tensor or just using temporal tensor.
