Add tests which exercise more complex JUnit extensions

[holly-cummins]

We have several scenarios at the moment which don't work, and we don't have tests covering them. I've added (disabled) tests for these scenarios, in preparation for enabling them alongside a fix.

I wasn't totally sure what the best home was. I considered putting these tests in the maven project, test-extension, or in a new project dedicated to the test framework. In the end, I put them in the test-extension project, since it would often be extensions that were defining these kinds of JUnit extensions.

What’s in this PR?

• Update to the test parents to allow children to specify a non-default port. This is needed because once a module defines a few LaunchMojoTest descendants, which may then get run in parallel, there will be port conflicts. This ended up touching a lot of files.
• A disabled test for Quarkus CDI-managed beans not available in Pact state callbacks #22611.
• A disabled test for Templated test contexts do not see transformed test classes (classloader/ordering issues in tests) #27821.
• A disabled test for quarkus-pact #73, made more generic - no Pact

I've checked that when enabled, all of the tests fail for the expected reason. For example, the parameter test triggers a deep clone which can't succeed on Java 17+, so it fails with

I tried to add a test for #30317 (with an extension to bring in parent-first dependencies, a test application, and a test), but even on Quarkus 3.0.0.Alpha4, I couldn’t reproduce the original issue.

Wait, isn’t this change pointless since all the tests are disabled?

Well, sort of. But it’s a biiiiig changeset, and it would make #34681 even bigger if all this was included with all that. That would be no fun to review. Also, it’s useful to have a clean changeset in which I was able to confirm each new test failed if the implementation changes weren’t there.

I think this is ready for review. There are some failures in Windows on tests that I touched, but I think @aloubyansky mentioned that he'd seen them in other builds?

I think you could do the same as for the compiler plugin here.

@holly-cummins it looks ok to me except points in the test poms, could you check please?

#35195 shows the same JarRunnerIT faillure, so I think it's unrelated to my changes.
