[JENKINS-73824] Add test for deleting a Pipeline job while one of its builds is running only on a OneOffExecutor

See jenkinsci/jenkins#9790. Once I have an incremental build of that PR I will update this PR to consume it.

Testing done

Submitter checklist

• Link to relevant pull requests, esp. upstream and downstream changes
• Ensure you have provided tests - that demonstrates feature works or fixes the issue

The CodeQL autobuild doesn't like the HPI plugin override (interestingly I also get this error in Netbeans, but it works fine using Maven directly):

[2024-09-27 19:27:07] [autobuild] org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:
Error: 9-27 19:27:07] [autobuild] [ERROR] Unknown packaging: hpi @ org.jenkins-ci.plugins.workflow:workflow-job:${changelist}, /home/runner/work/workflow-job-plugin/workflow-job-plugin/pom.xml, line 37, column 16

I suspect that a release of jenkinsci/plugin-pom#1004 would help, but I have not tried to investigate the issue deeply.

Is there any reason for this to still be in draft?

[dwnusbaum]

Given this PR just adds a test, I am not sure if we actually want to merge this as-is, or would prefer to wait for JENKINS-73824 to possibly get backported to 2.479.x.

Oh OK, it is an lts-candidate.

Integrated into #470 for simplicity.
