…numerable<ListViewItem>`, which necessitates unnecessary array allocations when adding from a collection. It also doesn't implement a generic `IList<T>` which makes typed usage and LINQ usage difficult. This adds that. Also add `IEnumerable<Control>` to `ControlCollection` to address the LINQ scenario. Control has `IList`, but indexed setting throws. I don't want to add `IList<Control>` until we've had time to evaluate the implications of implicitly doing the public steps with the collection that replicate what those setters should be doing. Also tweak `ArrangedElementCollection` so the static empty collection can't be written to. This doesn't fix the ambiguity of `AddRange([..])` with `ListViewItemCollection`, but it does avoid the need for it in some cases.
