[Quant] Fix accuracy_level config option for MatMul 4bits quantizer (#20146) ### Description Fixes code that extracts the accuracy level when creating a MatMulNBits node in the `DefaultWeightOnlyQuantizer` class. ### Motivation and Context Error from line 443: `AttributeError: 'DefaultWeightOnlyQuantizer' object has no attribute 'accuracy_level'`. The solution is to access `self.config.accuracy_level` instead of `self.accuracy_level`. Relevant commit: https://github.com/microsoft/onnxruntime/pull/19106
