helium/utils/depot_tools.patch

# Changes to gclient that:
#   use system python on windows
#   move dotfiles into the staging directory
#   skip cipd binary downloads
#   skip gcs downloads unless its an allowed sysroot
#   replace 'src' in checkout paths with the output directory
#   add flag to specify an allowed sysroot
#   ensure shallow fetches
#   utilize a newer version of gsutil to support later versions of python
#   allow StrEnum-equivalent functionality on older python
