Fix Configuration with IList and ICollection

[tarekgh]

#77725

In .NET 7.0 we had some code refactoring and fixes in configuration. This change had been handling the binding to ICollction<T> and IList<T> by creating underlying Array<T> object. It is obvious the returned object is not expandable which means users cannot add more items to that object. This is wrong and regression from previous versions of .NET/Core. The fix here is in case of binding to ICollction<T> and IList<T>, we'll create List<T> object instead which is expandable and allow adding more items to such object.

#77725 is a good example demonstrating this problem.
