New benchmark workflow (#1975)

# Goal
The goal of this PR is to create a new flow for benchmarks so that they
are easier to run and do not require a separate github token.

To test this must be in main as `workflow_dispatch` doesn't work without
being in `main`, but here is a run that was triggered using defaults
with a few other tweaks:
https://github.com/frequency-chain/frequency/actions/runs/9174859575

# Discussion
- The PR #1971 will remove the old system from the
`.github/workflows/verify-pr-commit.yml` file so that only this one is
used
- Once PR #1971 is merged, I will also update the wiki with the new
instructions
