[bindings] refactor NuGet packages

Declare .NET native dependencies per-plaftorm in `runtime.json`. Helps consumer apps only download and use the relevant native package for the desired OS/arch. Apps which need the native dependencies in their build output dir should consider https://learn.microsoft.com/en-us/dotnet/core/project-sdk/msbuild-props#enabledynamicloading or, alternatively, rely on `dotnet publish -r <RID>`.
