Refactor post-install script for modular component downloads

Introduces a DownloadUrls.psd1 manifest for component URLs and refactors postInstall.ps1 to support modular, architecture-aware downloads and installations. Adds selection logic for components, improves error handling, and updates setup.iss to support new GTK3 and GTK-server options. This change enables easier maintenance and extensibility for future components.
