[plugin][benchmark] upload OOT benchmark results to OOB dashboard

[gbyu-amd]

Motivation

This PR enhanced the OOT benchmark workflow to automatically upload the benchmark results to OOB dashboard as well.
Since OOB dashboard requires the benchmark results to be uploaded as an excel file with some specific format, a new script was added to process the data:

• .github/scripts/oot_benchmark_to_oob_dashboard.py

Similarly, the OOT benchmark workflow was updated to make the uploading optional when running the benchmark:

Since OOB data upload requires a password, a new repo secret, namely OOB_BENCHMARK_DATA_UPLOAD_PW, has been added in the settings.

If benchmark finished and upload succeed, a screenshot will be saved to indicate the status. The following image comes with this run: https://github.com/ROCm/ATOM/actions/runs/24074200879, where gpt-oss and kimi k2 were selected as an example.

The data shown in OOB dashboard is aligned with the ones from benchmark run.

Test Plan

Manually trigger a benchmark run to verify the functionality.

Test Result

The benchmark data has been successfully uploaded as expected.
