[clang-format] Disable progress bar if stdout is piped (#36955) Summary: **Summary** This commit disables the progress bar for the `clang-format` binary download if stdout is not attached to a terminal. The cursor repositioning tricks used to print out the progress bar don't work if stdout is redirected something that is not a terminal, and so the file ends up containing each progress bar update on a separate line. This happens in the GitHub workflow for checking formatting and is annoying to scroll through. **Test Plan** 1. Manual invocation of the script still produces progress bar. ``` (pytorch) me@devgpuXXX:pytorch (disable-cf-progress-bar)$ with-proxy tools/clang_format.py Downloading clang-format to /home/me/local/repos/pytorch/.clang-format-bin 0% |################################################################| 100% Using clang-format located at /home/me/local/repos/pytorch/.clang-format-bin/clang-format ``` 2. GitHub `clang-format` workflow output no longer contains progress bar. ``` Run set -eux + echo '~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + echo '| Run tools/clang_format.py to fix formatting errors |' | Run tools/clang_format.py to fix formatting errors | + echo '~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + tools/clang_format.py --verbose --diff Created directory /home/runner/work/pytorch/pytorch/.clang-format-bin for clang-format binary Downloading clang-format to /home/runner/work/pytorch/pytorch/.clang-format-bin Reference Hash: d1365110da598d148d8143a7f2ccfd8bac7df499 Actual Hash: d1365110da598d148d8143a7f2ccfd8bac7df499 Using clang-format located at /home/runner/work/pytorch/pytorch/.clang-format-bin/clang-format All files formatted correctly ``` **Fixes** This PR fixes https://github.com/pytorch/pytorch/issues/36949.
