Grid: cannot bind selection to signal

[stefanuebe]

Description

I tried to bind the selection to a signal, but that fails with an exception:

Caused by: java.lang.UnsupportedOperationException: Binding value to a Signal is not supported by 
	at com.vaadin.flow.component.HasValue.bindValue(HasValue.java:312)

Expected outcome

Grid selection should support signals via bindValue.

Minimal reproducible example

public class GridView extends VerticalLayout {

    public GridView(UserSettings userSettings) {

        Grid<Object> grid = new Grid<>();
        grid.setSelectionMode(Grid.SelectionMode.MULTI);
        var signal = new ValueSignal<Set<Object>>(new HashSet<>());
        grid.asMultiSelect().bindValue(signal, signal::set);
    }
}

Steps to reproduce

Add the snippet and open the respective view. It will fail immediately

Environment

Vaadin version(s): 25.1.0-beta3
