Mason Daugherty f2d3a2f6e2 fix(infra): skip codspeed for partners without benchmarks (#36775)
The CodSpeed workflow was failing on partner PRs because `check_diff.py`
added every partner to the `codspeed` matrix unconditionally — even when
no `tests/benchmarks/` directory exists. The workflow then ran an empty
shell block for those partners, CodSpeed saw zero benchmarks, and marked
the check as failed.

Currently no partner package has benchmarks, so this affected every
partner PR.

# Runs benchmarks on changed packages and uploads results to CodSpeed.
# Separated from the main CI workflow so that push-to-master baseline runs
# are never cancelled by subsequent merges (cancel-in-progress is only
# enabled for pull_request events).
