Add an extension method for BindableLayout's ItemSource that takes IEnumerable<T> as its parameter.

This enables using the Collection Expression to define the items collection.

public static TLayout ItemsSource<TLayout, T>(this TLayout layout, IEnumerable<T> items) {}

Usage:

new StackLayout()
    .ItemTemplate(() => new Label().Bind())
    .ItemsSource(["Red", "Green", "Blue"]);
