pytorch#178466 moved the CPU int8 fusion patterns out of inductor and into torchao. The fusion is now only registered when importing torchao.quantization.pt2e.quantizer.x86_inductor_quantizer. Without importing the file, eager quantize_ flow stopped lowering to onednn::qlinear and fell back to aten ops on cpu. The PR adds registrations from the int8 transforms in quant_api.
