Get https://github.com/pytorch/benchmark working
Labels: module: windows, triaged

### Description
- The https://github.com/pytorch/benchmark seems to be the official PyTorch performance benchmark running on the CI.
- This is a subtask of https://github.com/microsoft/ARM-on-Windows-Ecosystem/issues/187

### Acceptance Criteria
- We can compare results of https://github.com/pytorch/benchmark on Windows and WSL.

### Documentation

Steps to make this benchmark working:
- Enable long file names policy [Make Windows 11 Accept File Paths over 260 Characters (thegeekpage.com)](https://thegeekpage.com/make-windows-11-accept-file-paths-over-260-characters/) 
  - Still an issue [Add long path support for Windows [Approach #2] by majaeger · Pull Request #2056 · ninja-build/ninja (github.com)](https://github.com/ninja-build/ninja/pull/2056) 
- `conda create -n pytorch-benchmark-py3.8 python=3.8`
- `conda activate pytorch-benchmark-py3.8`
- `conda install -y -c pytorch pytorch torchvision torchtext`
- `conda install git-lfs pyyaml`
- `git clone https://github.com/pytorch/benchmark`
- Apply the following patch:
