Subject: [PATCH] [ci] Backport Buildkite PR pipeline to 8.11

This is a backport of the initial Pull Request pipeline for Buildkite.

While currently we haven't migrated all PR jobs from Jenkins, this is
needed so PRs against non `main` branches don't fail this step (also
giving us the possibility to test functionality against non `main`
branches).

- #15413

- #15421
