UserPermissionsForm should filter authenticated user permissions from other roles on save

Not entirely sure this is the desired behaviour, as currently you can untick "authenticated user" again and the permissions apply to the original roles again, but it does clean up role storage (and dependencies) a bit on complex sites with many roles and permissions in play.

Even though it's a task could we get test coverage.

The idea makes sense though, least to me. Probably would of helped some during the D9->D10 jump when having to fix bad permissions. Had to manually open the yml files to find the permission.
