[quant][core][performance] Changed cudnn quantized conv2d impl to use inplace operations (#73857) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/73857 This PR changed the implementation for the conv2d cudnn operator to use inplace ops. This increases the quantized conv operator's efficiency when bias and/or relu is used. Based on discussions, to support inplace operations, unique uids need to be assigned to the input and output even if it is stored at the same memory address. e.g., see the different uids in the current implementation assigned to conv_output.data_ptr Test Plan: In pytorch main directory, execute ``` python test/test_quantization.py TestQuantizedConv.test_qconv2d_cudnn ``` for accuracy testing and ``` python test/test_quantization.py TestQuantizedConv.test_benchmark ``` for benchmark testing.
