Empty states: Making icon and/or title optional

[alinagast]

The empty state should be flexible enough to adapt to the height of its container.
For instance, in cards/widgets with a height of only one or two rows, the standard empty state does not fit properly into the available space. We are using the empty states not only in cards and tables but also in Dashboard widgets. Sometimes the situation arises that some widgets can show the content inside and sometimes the content cannot be loaded and we display an empty state instead. Depending on the height of the widget the empty state gets cut off.
Therefore, I would like to have an adaptable empty state component. So depending on the content or card height, the icon and/or the title should be optional.

Daniela Biasi is aware about the topic.

@alinagast this makes sense, i'll take over and do some specs so we can implement it :)
