Refactor Windows installer progress macros for improved clarity and functionality

- Introduced new macros for various installation progress stages, enhancing readability and maintainability of the installer script.
- Updated the progress reporting in the `farmcontrol.nsi` file to utilize the new macros, ensuring consistent progress tracking during installation.
- Adjusted the `winappupdate.js` file to align with the new progress constants, improving the accuracy of progress percentage calculations.
