[FR] iOS Resolver support for mixing cocoapods static and dynamic linking

### Feature proposal

* EDM4U Component: iOS Resolver

Have you thought about adding support for the [`cocoapods-pod-linkage`](https://github.com/microsoft/cocoapods-pod-linkage) plugin? As explained [in this post](
https://medium.com/microsoft-mobile-engineering/mixing-static-and-dynamic-linking-in-cocoapods-83b6d4252c59) cocoapods only allows to specify one type of linking for all the pods. This is specially a problem when having multiple targets like it is the case with the Unity Xcode project after they changed to use a `UnityFramework` library. We have this problem when integrating different Ironsource adapters where some of them should use static and some of them should use dynamic linking.
