47c566eb - Rename namespace `vec256` to `vec`, struct `Vec256` to `Vectorized` (and other related classes/structs) (#58438)

Rename namespace `vec256` to `vec`, struct `Vec256` to `Vectorized` (and other related classes/structs) (#58438) Summary: In order to make it more convenient for maintainers to review the ATen AVX512 implementation, the namespace `vec256` is being renamed to `vec` in this PR, as modifying 77 files & creating 2 new files only took a few minutes, as these changes aren't significant, so fewer files would've to be reviewed while reviewing https://github.com/pytorch/pytorch/issues/56992. The struct `Vec256` is not being renamed to `Vec`, but `Vectorized` instead, because there are some `using Vec=` statements in the codebase, so renaming it to `Vectorized` was more convenient. However, I can still rename it to `Vec`, if required. ### Changes made in this PR - Created `aten/src/ATen/cpu/vec` with subdirectory `vec256` (vec512 would be added via https://github.com/pytorch/pytorch/issues/56992). The changes were made in this manner - 1. First, a script was run to rename `vec256` to `vec` & `Vec` to `Vectorized` - ``` # Ref: https://stackoverflow.com/a/20721292 cd aten/src grep -rli 'vec256\/vec256\.h' * | xargs -i@ sed -i 's/vec256\/vec256\.h/vec\/vec\.h/g' @ grep -rli 'vec256\/functional\.h' * | xargs -i@ sed -i 's/vec256\/functional\.h/vec\/functional\.h/g' @ grep -rli 'vec256\/intrinsics\.h' * | xargs -i@ sed -i 's/vec256\/intrinsics\.h/vec\/vec256\/intrinsics\.h/g' @ grep -rli 'namespace vec256' * | xargs -i@ sed -i 's/namespace vec256/namespace vec/g' @ grep -rli 'Vec256' * | xargs -i@ sed -i 's/Vec256/Vectorized/g' @ grep -rli 'vec256\:\:' * | xargs -i@ sed -i 's/vec256\:\:/vec\:\:/g' @ grep -rli 'at\:\:vec256' * | xargs -i@ sed -i 's/at\:\:vec256/at\:\:vec/g' @ cd ATen/cpu mkdir vec mv vec256 vec cd vec/vec256 grep -rli 'cpu\/vec256\/' * | xargs -i@ sed -i 's/cpu\/vec256\//cpu\/vec\/vec256\//g' @ grep -rli 'vec\/vec\.h' * | xargs -i@ sed -i 's/vec\/vec\.h/vec\/vec256\.h/g' @ ``` 2. `vec256` & `VEC256` were replaced with `vec` & `VEC` respectively in 4 CMake files. 3. In `pytorch_vec/aten/src/ATen/test/`, `vec256_test_all_types.h` & `vec256_test_all_types.cpp` were renamed. 4. `pytorch_vec/aten/src/ATen/cpu/vec/vec.h` & `pytorch_vec/aten/src/ATen/cpu/vec/functional.h` were created. Both currently have one line each & would have 5 when AVX512 support would be added for ATen.
