Create a generic system to provide menu based navigation blocks

This has come up in the past. Personally, I'm a fan of the deriver plugin approach. I think it provides a lot of flexibility for sites that really want to take control of their sidebar which would be really neat.

One thing we'll have to address, (which we have to do now anyway), is a better visual icon fallback than we currently have when the CSS class doesn't match up with what we already support. You can see that already with the Announcements menu item, which I think was added in 10.2. That can be a seperate issue though.

@m4olivei went ahead and worked on a POC for the deriver approach.

Now, every menu has automatically created its own configurable navigation blocks.

This configuration allows to exclude items, so big part of the concerns in 📌 Adjust how Help link and Content links are removed from the Administration menu for the Navigation bar RTBC could be addressed in this issue.

So good! I'll leave the issue as Needs Review for others to take a look as well, as it's a decent size change, and their might be opinions.

Logic to exclude items dynamically from the navigation block config has been removed, as agreed on weekly call.

Discussion about how to exclude items in a generic and non-intrusive way can be moved to #3415572

Just a few small things to address. See MR threads.

Thank you for your feedback @m4olivei!

I think it has been addressed. Please take a look again once you get the chance.

@plopesc Hum, I don't see new commits? Last commit was Feb 1. Maybe you forgot to push them up?

Yes, you were right.

Hit enter, but did not check if the operation was successful. It should be there now.

Sorry for the inconvenience.

Merged!
