ListItem doesn't support isEnabled state.

[jodator]

The ListItem used in dropdowns doesn't support enabling/disabling it.

I think that one could set some list items as disabled especially if one is creating dropdown with multiple commands as items:

const command = editor.commands.get( commandName );

const itemModel = new Model( {
	commandName,
	label
} );

itemModel.bind( 'isEnabled' ).to( command );

dropdownItems.add( itemModel );


addListToDropdown( dropdownView, dropdownItems );

Setting isEnabled to false should gray-out the item.
