Switching to DependencyPropertyGenerator

[HavenDV]

Is your feature request related to a problem? Please describe. This will remove a lot of boiler-plate code from the project, make the DP code multi-platform, making it easier to migrate to WinUI/Uno in the future if it happens. It also simplifies project maintenance and development by reducing code complexity. I could provide small PRs to ensure easy validation and a smooth transition.
