Add ProgramIconChecksums table

[cesarfda]

This pull request introduces a new osquery table for Windows called kolide_program_icon_checksums, which provides checksums for program icons without including the icon data itself. The implementation refactors existing code to support this new functionality and improves the flexibility of icon data collection.

Closes #2401

New Table Addition:

• Added the kolide_program_icon_checksums table to the platform-specific tables for Windows, allowing users to query program icon hashes alongside program names and versions, but without the icon image data. [1] [2]

Refactoring for Data Collection:

• Refactored the icon data generation functions (generateUninstallerProgramIcons and generateInstallersProgramIcons) to accept an includeIcon parameter, enabling reuse of logic for both tables and controlling whether icon image data is included in the results. [1] [2] [3] [4]

Implementation Details:

• Updated the logic in both icon generation functions to conditionally include the "icon" field in the result map based on the includeIcon parameter, ensuring the correct schema for each table. [1] [2]
• Created the generateProgramIconChecksums function to aggregate program icon hashes for the new table, leveraging the refactored icon generation functions with includeIcon set to false.

These changes improve the flexibility and maintainability of the program icon tables, allowing for both detailed icon data and lightweight checksum queries.
