This reverts commit 7cfd23636c8fa6fcbb8bf3ea34e15b847ec9ad9d. Reverted https://github.com/pytorch/pytorch/pull/134935 on behalf of https://github.com/izaitsevfb due to breaks internal builds, caffe2 is still used internally ([comment](https://github.com/pytorch/pytorch/pull/134935#issuecomment-2349368152))
