Those actions are just separators having also text and potentially icon.
It is very convenient to create titled sections in a menu, or give a
title to a context menu.
Obviously requires support for them on the style side, but modern styles
like fusion or oxygen handle them just fine. For legacy styles it
properly falls back to a regular separator aspect. That's why a specific
style hint is also introduced. It is used by QMenu to know how the
sections will be treated and take care of them correctly when
eliminating duplicated separators or separators at the beginning of the
menu.
