This pull request introduces a standardized YAML-based configuration system for transformer attention benchmarks, making it easier to run and manage comprehensive performance tests. It adds example configs, and a wrapper script to convert YAML configs into CLI arguments for the benchmark runner.
#### Next Steps:
CI Enablement: This change would further lead to running the attention ops in CI for regression tracking.
#### Developer flow: (Run locally)
`python score_mod.py --config configs/config_test.yaml`
