Migrate Syscollector to Inventory at new-agent repository

[nbertoldo]

This PR migrates Syscollector module from the wazuh/wazuh repository to the wazuh/wazuh-agent repository as described in #17.

Description

This PR migrates the Syscollector module from the wazuh/wazuh repository to the wazuh/wazuh-agent repository, following the tasks outlined in #15. This migration is part of the ongoing effort to modularize components in the agent repository. It involves refactoring code, adapting to the new repository structure, and ensuring that the migrated modules (Syscollector and DBsync) function correctly in the new environment.

Changes

Code Migration:

• Migrated the Syscollector and DBsync code from the wazuh/wazuh repository to the wazuh/wazuh-agent repository.
• Refactored classes, functions, and variable names to fit the new modular architecture (renamed "Syscollector" to "Inventory").
• Updated the CMake files and added new dependencies supported by vcpkg.

Integration with Queue:

• Integrated Syscollector (now Inventory) with the new Queue component, ensuring the proper handling of messages.

Dependencies:

• Migrated dependencies such as libdb, pacman, procps, and rpm to vcpkg where possible.
• Removed unsupported or redundant libraries, including rsync.

Testing & Validation:

• Added new tests for the migrated modules (Inventory, DBsync, and the new module manager).
• Ensured compatibility with Windows by adapting the code for MSVC compilation.
• Refactored logging mechanisms to align with the new Logger implementation.

Code Cleanup:

• Removed legacy code for unsupported operating systems.
• Refined the code by analyzing if the http-request used by data-provider could be removed.

Proposal

• Complete migration and ensure all related modules (Inventory, DBsync) work correctly after refactoring and integration.
• Address any missing dependencies by researching how to integrate unsupported packages into vcpkg or finding alternatives.
• Finalize tests and run validation to ensure no regressions occur in functionality.

Tests

• Compilation succeeded across all supported platforms (including Windows with MSVC).
• Validated package installation and upgrades.
• Unit and integration tests for Syscollector (Inventory) and DBsync passed successfully.

Tasks

• Identify the code in the wazuh/wazuh repository.
• Migrate the code to the wazuh/wazuh-agent repository.
• Refactor the code as necessary to fit the new repository structure.
• Test the migrated code to ensure it works correctly in the new repository.

Are the UT of the new modules/components running in the GHA workflows (Linux, Windows and macOS)?
