VwcButton and in general buttons support the value attribute, but VwcIconButton is missing it. It is missing also in Vivid docs, but if we force it on it it's working properly.
VwcButton with icon won't suffice as it has different shape than VwcIconButton. Under the hood, VwcIconButton is using MWCIconButton which is extending html button, which by default support value.
