Subject: Add concurrency cancellation for test/build GitHub Actions (#2710)

The GitHub Actions build queue can get 'stacked up' if there are a few smaller commits in quick succession. Since the actions take some time, some small commits can cause the GHA build queue to get congested.

This adds a 'concurrency' check for GitHub actions. It means that if a newer trigger comes in (for example, if you make two commits in a row on a PR), then the first job will be cancelled, allowing for the new job to run.

This helps save energy, and for faster feedback in PRs.
