3e307c25 - [quant][gpu][core] Implemented quantized add operator using cudnn (#74463)

[quant][gpu][core] Implemented quantized add operator using cudnn (#74463) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/74463 This PR implements the quantized add operator using cudnn operations. Also added a corresponding test function in test_quantized_op.py. Ideally, we should merge this function with the cpu variant, but for now, we will keep it separate until cudnn v8 is in the default build. Other factors also complicate the merge as cudnn quantized add is currently only supported for int8 symmetrically quantized tensors. Test Plan: In pytorch main dir, execute ``` python test/test_quantization.py TestQuantizedOps.test_qadd_relu_cudnn ``` TBA Differential Revision: D35009111 D35009111 Reviewed By: jerryzh168 Pulled By: dzdang fbshipit-source-id: 13afa7f0192ffaf1f36334b1af827202c7dd0f74 (cherry picked from commit 2b5759523e2fec5c849941552b904e412d67a138)
