[quant][graphmode][fx][fix] scalar as first input for add/mul (#46751)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/46751
Currently we assume the first input for add/mul is node (Tensor), but it might not be the case
Test Plan:
python test/test_quantization.py TestQuantizeFxOps.test_quantized_add
python test/test_quantization.py TestQuantizeFxOps.test_quantized_mul
python test/test_quantization.py TestQuantizeFxOps.test_quantized_add_relu
python test/test_quantization.py TestQuantizeFxOps.test_quantized_mul_relu
