Show pipeline iid in pipelines page

Problem to solve

IID was added in [11.0] and is useful for things like semver, but not exposed anywhere in the UI. We're considering chaning the routing of pipelines to match IID which would be valuable, but maybe a breaking change for some use cases. Before doing that, we could add IID to the user interface elsewhere (for instance the pipelines page).

Today we have added with https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/26853 the Pipeline IID right next to the pipeline ID which can be very confusing for even advanced GitLab users:

Target audience

• Delaney, Development Team Lead, https://design.gitlab.com/research/personas#persona-delaney
• Sasha, Software Developer, https://design.gitlab.com/research/personas#persona-sasha
• Devon, DevOps Engineer, https://design.gitlab.com/research/personas#persona-devon

Further details

This will help make CI more lovable, per our "Lovable" north star.

Proposal

Originally rom https://gitlab.com/gitlab-org/gitlab-ce/issues/44083#note_90864707

Place the Pipeline's IID here:

What does success look like, and how can we measure that?
