[Infra] Add GHA behavior where old workflows are cancelled when new commit is pushed to a PR (#9498)

* Add top-level concurrency context to all workflows

* [will revert] Kill all workflows from previous commit

* [skip ci] Revert "[will revert] Kill all workflows from previous commit"

This reverts commit c6cf40a.

* [skip ci] Don't cancel in progress for `generate_issues.yml`

* Experiment with conditonal cancellation

* [keep ci] this would be cool if it worked

* Try again

* [keep ci] try again

* Undo experiment and try to cancel `health-metrics-*`

* [skip ci] Revert `health-metrics-presubmit.yml`
