Show linked pipelines mini graph in the pipeline editor

This adds the upstream/downstream pipeline mini graphs in the pipeline editor.

This feature is under the pipeline_editor_mini_graph feature
flag, which is currently disabled. This reverts
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/72951
and splits the specs so that the ce and ee tests are separated.
