Convert conv_prepack to conv2d_prepack and conv_unpack to conv2d_unpack (#29529)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/29529
Pull Request resolved: https://github.com/pytorch/glow/pull/3771
We would like to replace `conv_prepack` with `conv2d_prepack` and `conv_unpack` with `conv2d_unpack`.
This makes the naming consistent between 2D and 3D conv:
```
torch.ops.quantized.conv2d_prepack
torch.ops.quantized.conv2d_unpack
torch.ops.quantized.conv2d
torch.ops.quantized.conv3d_prepack
torch.ops.quantized.conv3d_unpack
torch.ops.quantized.conv3d
```
We should do this earlier rather than later when we have more users for the quantized conv2d ops, for better engineering.
The replacement bash command is as the follows:
```
find ./ -type f -exec sed -i -e 's/quantized::conv_prepack/quantized::conv2d_prepack/g' {} \;
find ./ -type f -exec sed -i -e 's/quantized::conv_unpack/quantized::conv2d_unpack/g' {} \;
find ./ -type f -exec sed -i -e 's/torch.ops.quantized.conv_prepack/torch.ops.quantized.conv2d_prepack/g' {} \;
find ./ -type f -exec sed -i -e 's/torch.ops.quantized.conv_unpack/torch.ops.quantized.conv2d_unpack/g' {} \;
```
