Verbatim copy of .github/workflows/abi.yaml from rolling (#3262, #3276, #3340, #3341). Without it, pull requests targeting kilted get neither the ABI check nor the "ABI compatible" / "ABI break" and backport- labels, because pull_request workflows run from the workflow file of the target branch.

Only abi.yaml is needed here: the sticky comment and the labels are published by abi-report.yaml, a workflow_run workflow, which GitHub always runs from the default branch (rolling). The distro and the REP-0009 policy are resolved from the target branch (distro: auto, policy: auto), so the check is strict on kilted: an incompatible ABI change fails the check.

Verified with the same file on test pull request(s) #3387 (compatible).
