* Device side PTQ API.
* Once the model has been prepared for quantization on server side, such model
* is sent to device. On device side the model is further trained. At the end of
* the training, before the model is readied for inference, we need to quantize
* the model.
* Usage of this API is as follows.
* PTQQuanizationHelper ptq_helper;
* ptq_helper.quantize_dynamic(m, "forward");
* Args:
* m: Captured by reference, an instance of mobile::Module. This module will be
* mutated in place to replace its <method_name> method with quantized
* equivalent. method:name: Name of the method to be quantized. AOT preparation
* for quantization must also have been done for this method. Returns: In place
* mutated `m` whose size should be smaller due to weight quantization and whose
* <method_name> method should use quantized ops
