List currently assigned reviewers in the reviewers drawer

In the reviewers drawer component we need to list the currently assigned reviewers with their reviewer state in the reviewers drawer component. See the design #441689[reviewer-assignment.png]

Note This also needs to include the empty state illustration and the assign yourself button

Maybe we can use the current component for this https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/sidebar/components/reviewers/uncollapsed_reviewer_list.vue?
