[quant][core][gpu][improvement] Set tensors as virtual in quantized cudnn linear op Summary: For cudnn, if certain intermediate tensors are not needed for other parts of the operation graph in cudnn, the it can be set as virtual, so that a pointer-uid pair does not need to be provided for the variant pack, allowing for better performance. Test plan: ``` python test/test_quantization.py -k test_qlinear_cudnn ``` Pull Request resolved: https://github.com/pytorch/pytorch/pull/75967 Approved by: https://github.com/jerryzh168
