Resolve "change status icon for reports when fails to be found or cannot load"

What does this MR do?

• Updates svg dependency
• Updates icon usage
• Updates CSS

Are there points in the code the reviewer needs to double check?

I removed CSS that I believe is not being used for not-found icon. The not found icon is called notfound in the svg repo.

I created a backport MR for CE with the common changes: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/16616
