feat(buildimages)!:Adapt tasks to handle new images

[chouetz]

What does this PR do?

Update the buildimages tasks to be able to handle the new CI_IMAGE_ buildimage variables. I also introduced these new images (not used yet) to prepare migration

Motivation

Smart build of buildimage, capacity to build & promote a set of images to datadog-agent

Describe how to test/QA your changes

UT + local manual tests

Possible Drawbacks / Trade-offs

This is a breaking change in the buildimages.update task. I also decided to change the test_version argument to test and aligned everywhere, so increased the impact of this PR

Additional Notes

Based on previous changes, #30365 and #30370
