Add Auto DevOps alert to Security Configuration page

What does this MR do?

This is adds the Auto DevOps alert as described in #220573 (closed).

This alert is displayed only when all the following is true:

1. A project has no existing .gitlab-ci.yml file
2. Auto DevOps is not enabled for the project
3. The user has the necessary permissions to enable Auto DevOps for the project
4. The sast_configuration_by_click feature flag is enabled (it's currently disabled by default)

Note

While this frontend work depends on the backend work being done, because this is behind a feature flag, it should be safe to merge in any order.

Testing locally

1. Merge (or cherry-pick) the backend work done in !36225 (merged) into this branch locally
2. Enable the sast_configuration_by_click feature flag
3. Navigate to or set up a project that satisfies the above requirements
