Porting SpatialDilatedConvolution and VolumetricDilatedConvolution to ATen (#20983)
Summary:
This PR tackles issue https://github.com/pytorch/pytorch/issues/18352 .
Progress:
- [x] conv_dilated2d CPU
- [x] conv_dilated3d CPU
- [x] conv_dilated2d CUDA
- [x] conv_dilated3d CUDA
- [x] RocM port
- [x] Port of CUDA gemm and gemv
- [x] Refactored 2d and 3d functions as well as output and gradient computations into a single C++ template function
- [x] Cleanup
+ [x] eliminate forward functions
+ [x] eliminate buffers `columns` and `ones` from functions API
+ [x] eliminate out functions
+ [x] eliminate using `ones`
Note that col2im, im2col, col2vol, vol2col implementations are exposed in `ATen/native/im2col.h` and `ATen/native/vol2col.h`. The corresponding operators (not ported in this PR) should use these.
