Performance tracking (comment) #576

# To workaroud https://github.com/actions/first-interaction/issues/10 in a secure way,
# we take the following steps to generate and comment a performance benchmark result:
# 1. first "performance tracking" workflow will generate the benchmark results in an unprivileged environment triggered on `pull_request` event
# 2. then this "performance tracking (comment)" workflow will show the result to us as a PR comment in a privileged environment
# Note that this workflow can only be modifed by getting checked-in to the default branch
# and thus is secure even though this workflow is granted with write permissions, etc.
# xref: https://securitylab.github.com/research/github-actions-preventing-pwn-requests/
