Reproduce Repository X-Ray functionality in GitLab Rails monolith

Summary

In #474306 (comment 2025085630), we decided to migrate the Repository X-Ray functionality into the GitLab Rails monolith. This will allow us to run the service outside of the CI pipeline.

Proposal

Reproduce the functionality in Repository X-Ray as a new service inside the GitLab monolith.
