update runHLTTiming script to be more modular

[mmusich]

PR description:

This PR refactors the benchmarking script by introducing two helper functions, run_cmsdriver and run_benchmark, in order to reduce code duplication and improve maintainability.

The main changes are:

• Extract the repeated cmsDriver.py invocation into a reusable function run_cmsdriver.
• Extract the repeated patatrack-scripts/benchmark workflow into a reusable function run_benchmark.
• Keep the overall script structure and execution flow unchanged to preserve the current behavior.

No changes are expected in the output of the script. The refactoring is purely structural and intended to make future modifications (e.g. adding new menus or benchmark configurations) easier and less error-prone.

No additional dependencies are introduced and this PR does not depend on other PRs.

PR validation:

Will rely on the testing from the bot.
Since this change only reorganizes existing code without altering the workflow logic, no additional unit tests or matrix workflows were required.
