chore(GlInfiniteScroll): fix stories
This fixes a few things in GlInfiniteScroll stories:
- Ensure GlLoadingIcon is properly registered.
- Prevent props names conflicts by renaming a few things and leveraging watchers.
- Don't override the default slot unless the isLoading prop is true.
This will help us showcase the component in design.gitlab.com as part of gitlab-org/gitlab-services/design.gitlab.com#1306 (closed).
