For OxyPlot.Xamarin.Android, OxyPlot.Xamarin.iOS and OxyPlot.Xamarin.Mac, this migration was done automatically via VS2022. For the others projects this was not possible for some reason, so I simply removed the packages.config files there. It was not necessary to add any PackageReferences manually to make the solution build.
This PR migrates the OxyPlot.Xamarin.* projects to the newer PackageReference style and removes the packages.config files, see https://learn.microsoft.com/en-us/nuget/consume-packages/migrate-packages-config-to-package-reference
