Subject: [PATCH 7/8] Implement label select tooltip for issuables

Makes it possible to see the decription tooltip for a label inside the
label select dropdown for issues and merge requests when the feature
flag `:label_dropdown_tooltip` is enabled.

This does _not_ enable this for label editing interactions on work items
(tasks, OKRs) because a different component is used for label editing on
work items.
