Make the "more actions" functionality configurable

Thinking about that issue and finding others having problems with it (e.g. https://www.drupal.org/project/workflow/issues/3458569 ✨ Support Gin action item Active )- I have to say that I get the impression that there is something inherently wrong with the gin approach of putting its own functionality buttons above other modules.
Requiring the other modules to flag theme(!) specific attributes will only clutter the drupal code and cause
"Latest version of Gin Admin theme hides actions behind a more actions button unless it is identified as a #gin_action_item."

In how many modules do you expect to find #gin_action_item in the code?!

So I suggest:

Treat all functionality of any module as equal. Therefore making it configurable by admins: per entity type which buttons appear outside of the more actions menu and in which order.

I also think it is a major issue, since it concerns many other modules.

Also see this comment. https://www.drupal.org/project/save_edit/issues/3528935#comment-16138378 🐛 Save_edit in GIN admin theme in Drupal CMS (11) hardly accessible Active
It shows that is impossible to rely on gin functionality in this matter.

Changed to Major and BUG because it causes a lot of headaches outside of gin...
