Pass security configuration page data to Vue

What does this MR do?

• Adds /:namespace/:project/security/configuration route
• Adds Projects::Security::ConfigurationController
• Adds projects/security/configuration/show.html.haml with div#js-security-configuration
• Adds Projects::Security::ConfigurationPresenter
• Brings frontend variable naming related to Auto DevOps in line with backend (AutoDevOps -> AutoDevops)

The presenter contains most of the logic. It passes links to the security features' docs, a link to the project's latest pipeline, and the configuration status of each security feature to Vue as data attributes in the HAML template.

Frontend MR: !19554 (merged)
