Add a inference acceleration tutorial

Like what we did for training acceleration:

We can consider this for 1.5. This would use ONNX, TRT, something else you're thinking of?

Hi @ericspod , thanks for the suggestions!

Now I'm starting this work, the following features are considered to use:

1. GDS for data loading
2. do GPU transform
3. use TRT for inference

Except for the above features, @Nic-Ma also suggests to add quantization support, we can conduct adding this feature in the next version.
