[dev-v5] Add FluentListbox

Enhance the FluentListbox component with multi-select capabilities, improved keyboard navigation, and better event handling for listbox changes. Update documentation and examples to reflect these changes and ensure accessibility improvements. This update addresses usability and functionality for selecting multiple items in lists.

<FluentListbox Label="Color"
               Items="@Colors"
               @bind-Value="@Value" />

<div>Selected: <b>@Value</b></div>

@code {
    static string[] Colors = ["Red", "Green", "Blue"];
    string? Value = "Green";
}
