fix get power stats from turbostat for telemetry

[harp-intel]

This pull request refactors the logic for parsing turbostat output to improve how summary (platform) and package rows are identified and extracted. The changes introduce helper functions for clearer row classification and enhance compatibility with different turbostat output formats.

Row classification improvements:

• Added the isPlatformRow helper function to accurately identify platform (summary) rows by checking that Package, Die, Node, Core, and CPU are all "-" or missing. This replaces previous inline logic and improves maintainability.
• Updated the turbostatPlatformRows function to use isPlatformRow for filtering, ensuring only platform rows are returned.

Package row handling enhancements:

• Added the isPackageRow helper function to identify package rows where Package is present and not "-".
• Modified the turbostatPackageRows function to use isPackageRow and to handle cases where the Package column is missing by inferring package information from the CPU column. This improves robustness across different turbostat outputs.

Documentation updates:

• Improved function comments to clarify that only summary and package rows are returned, and updated descriptions to reflect the new logic for identifying row types. [1] [2]
