Gin toolbar should dynamically override libraries via hook_library_info_build()

Problem/Motivation

At the moment, gin toolbar adds it's libraries overrides via hook_library_info_alter() which does not run in the runtime, but during the container/cache rebuilds, which creates a problem of unintentional adding claro/gin css/js files to the frontend theme when the toolbar is not active (again, because library data is being cached). In my case it was a dialog css.
