.github: Add options to force unzip artifacts (pytorch#56929)

Summary:
Pull Request resolved: pytorch#56929

Artifacts were failing to unzip since they already existed in the
current tree so this just forces the zip to go through no matter what

Was observing that test phases will fail if attempting to zip over an already existing directory, https://github.com/pytorch/pytorch/runs/2424525136?check_suite_focus=true

In the long run however it'd be good to have these binaries built out as part of the regular cmake process instead of being one off builds like they are now

**NOTE**: This wouldn't be an issue if `--ephemeral` workers was a thing, see: actions/runner#660
