515d61f2 - [quant][core][bug fix] Corrected at::to(memory_format=...) support for quantized tensors

[quant][core][bug fix] Corrected at::to(memory_format=...) support for quantized tensors Summary: Previously, at::to support for quantized tensors did not work properly, and we had to, instead, use at::contiguous. This PR allows us to use at::to(memory_format=...) or torch.Tensor.to(memory_format=....) on the back- and front-ends. Test plan: python test/test_quantization.py -k test_qtensor_to_memory_format Pull Request resolved: https://github.com/pytorch/pytorch/pull/75540 Approved by: https://github.com/jerryzh168
