Feature: Split button

[bjarnef]

I noticed this and wonder if it would make sense to add a split button - e.g. a button as primary action + addition actions.

or

E.g. what used to be at "Save & Publish" + additional actions.

@iOvergaard @nielslyngsoe would something like this make sense?

Some also call this ButtonGroup with options/items/children:

UI library already has a uui-button-group component though:
