Add support for clearing the cache from the navigation menu

I'm also looking for this functionality.

This seems like good something a contrib module can fill in for, at least in the short term.

I have created a new module "Navigation Extra Tools", which replicates the functionality for the Admin Toolbar Extra Tools submodule.

Perhaps at some point it might make sense to merge into the core navigation. However, I'm happy to maintain as a contrib module as long as needed.

It's currently not covered by the security policy. I've applied for permission to add security coverage.

Does https://www.drupal.org/node/3414904 → mean this is no longer needed, as I think blocks can be placed in the navigation? I could be wrong!
