Subject: [PATCH] [ci] Specify limited concurrency for PR jobs

There was a concurrency setting we hadn't enabled on jobs that are primarily triggered for PRs. This meant that every update to the PR would trigger new CI jobs without canceling any ones already in flight, which can greatly slow down CI due to the number of jobs that need to run.

This PR adds concurrency [based on the workflow name and PR number or head ref.](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/control-the-concurrency-of-workflows-and-jobs)
