ci: cancel preceding workflows run

This patch adds concurrency groups to the CI workflows to automatically
cancel any in-progress workflows when a pull request has been updated.
A `concurrency` group allows to ensure that a single job or workflow
will run at a time. For example, when a pull request is updated with
a force-push, the GiHub CI workflows currently in-progress will be
automatically cancelled, and the CI would run only with the updated
commits.
