Description

IListProvider<T>.ToList() implementations in System.Linq for iterators of known lengths use list.Add(element) to initialize the list over directly writing to its underlying array.

This is to not forget to update the implementations once any of the following is done: #80311, #55217 or #80756.

Analysis

Once we have an API for direct List<T> initialization (aside from new List<T>(collection)), it's a good idea to utilize it in BCL to reduce the overhead.
