[quant] Support PerChannel quantization in FusedMovingAvgObsFakeQuantize (#62346)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/62346
Update the operator code to resize the min/max tensors if per-channel quant is selected. We need to do this because by default the observer creates empty tensors for min/max and scale/zero_point values when per-channel quantization is enabled
Test Plan:
python test/test_quantization.py test_fused_mod_per_channel
