Hide the block when there are no results

No configuration needed, should just not appear.
Instead it has the following content:

<div class="entity-submenu row gy-equal-x">
</div>

On it!

Originally it is:

<div class="entity-submenu">
</div>

"row gy-equal-x" comes from our template override.

@thomas.frobieter here we go! I finally decided for a setting, if someone needs this as fallback, because I saw these lines:

// Return empty menu items array if the active trail is not in this menu.
    if (empty($this->menuActiveTrail->getActiveLink($menu_name))) {
      return $build;
    }

So maybe it was intended to be rendered sometimes, even if there are no items.
The new setting allows to use the previous behavior, if needed.

Works well, thx!

Thanks, so let's merge this.
