[qunat][graphmode][fx] Add a separate lower_to_native_backend function for relu (#62861) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/62861 This PR adds a lower_to_native_backend function to lower a quantized reference model to a model that uses fbgemm/qnnpack ops. We'll gradually add support and remove the fbgemm/qnnpack specific handling in quantization_patterns.py Test Plan: python test/test_quantization.py TestQuantizeFx python test/test_quantization.py TestQuantizeFxOps Imported from OSS Reviewed By: vkuzo Differential Revision: D30165828 fbshipit-source-id: de1149cd7e7c1840c17c251cd4d35004afd015b7
