[ Mixed Precision ] Support Mixed Precision

This PR enables the Mixed Precision computation.
- Add the data_type property in Tensor : FP16, FP32
- Memory_Data only handle void *
- In Tensor, there were several member function with template
   : getAddress<float>() , getData<__fp16>, etc.
- Need to implement Blas Interface function
