Problem/Motivation
The default Dropdown button is being implemented on #3023243: Drop Buttons style update. This issue is a follow-up to get the primary one addressed. At the moment this is not being used anywhere so we want to implement it for potential contrib use cases.

Test Instructions
From comment #31 by @bnjmnm
A way to test the use of primary dropbuttons is with the Workbench Moderation module. If moderation is enabled on a content type, the submit button is converted to a dropbutton. (example: after enabling the module -- turn on moderation for the Article content type here /admin/structure/types/manage/article/moderation )
