Introduce feature flag to render pipeline with Vue [RUN AS-IF-FOSS] [RUN ALL RSPEC]

What does this MR do?

Depends on !55199 (merged)

This change adds introduces a feature flag to render the pipeline mini graph in the commit with Vue, this was historically implemented with HAML and jQuery.

☝ Enable ci_commit_pipeline_mini_graph_vue

Advantage:

• This change enables us to have a single source of markup for the mini pipeline graph
  • This will open the possibility of refactoring the CSS related to the mini pipeline, that is long overdue a refactor.
• Enables future removal of ~/mini_pipeline_graph_dropdown.js, a file that depends on jQuery
• Enables future migration to GraphQL as data format for all mini pipeline graph will be the same, however, more work is needed here.

Tradeoffs:

• We pass data to the frontend using JSON in a data-* attribute, which is inefficient.
  • This might be equivalent as we actually replace some HTML that is passed to the user.

Screenshots (strongly suggested)

Mini pipeline graph becomes consistent with the other pipeline graphs in the application:
