render flag help next to values for config command

[harp-intel]

This pull request refactors how configuration tables are generated and rendered in text reports, with a focus on improving clarity and usability for users of the config command. The main changes include adding command-line argument descriptions to each configuration field, introducing a custom text renderer for configuration tables, and simplifying report creation by removing unused parameters.

Configuration Table Improvements

• Added a Description field to each configuration item in the output of configurationTableValues, so the generated table now shows the corresponding command-line argument for each item [1] [2].
• Added a new function configurationTableTextRenderer that renders the configuration table in text reports, including field names, values, and their command-line descriptions for improved clarity.
• Updated the configuration table definition to use the new custom text renderer for text output.

Report Generation Simplification

• Removed the scriptOutputs parameter from the report.Create function and all its call sites, simplifying the report generation interface [1] [2] [3].

Additional Enhancements

• Added a helper function c6FromOutput to extract C6 state information for inclusion in the configuration table.
• Updated configuration fields for uncore frequencies, energy performance, scaling governor, efficiency latency control, prefetchers, C6, and C1 demotion to include their command-line argument descriptions [1] [2].

These changes make the configuration output more user-friendly and maintainable, while also streamlining the codebase by removing unnecessary parameters.

Pull request overview

This PR enhances the configuration table output to display command-line argument help text alongside configuration values. The changes make it easier for users to understand which command-line flag corresponds to each configuration setting by adding descriptions directly in the table output.

• Adds command-line argument descriptions to each configuration field
• Implements a custom text renderer for configuration tables that formats field names, values, and command-line flags
• Simplifies the report generation API by removing the unused scriptOutputs parameter
