FEATURE: Make MultiSelectBox drag&drop sorting feature optional

[Sebobo]

The MultiSelectBox in react-ui-components currently automatically makes all items draggable to allow changing the sorting. But this should be optional as not every use case needs this and then we have a feature that only confuses users.

Example: Sorting Tags and Collections for an Asset in the Media.UI has no benefit, see https://github.com/Flowpack/media-ui/issues/57

Example from the Demo:

I would like to do this at the next Neos Sprint. :)
