Create indexing-restrictions component
What does this MR do and why?
This creates the indexing-restrictions component which will replace
the current select2-based selector in the admin ElasticSearch indexing
restrictions settings.
This new component leverages GlCollapsibleListbox to fetch and present
available index entities. Selected entities are displayed in a
scrollable list below the selector and can be removed from there. A
hidden input is kept in sync with the selection.
For the sake of keeping the changes small, this only introduces the components and their tests. We'll actually use them in a follow-up.
