ci: add Pull Request Labeler

[mkroening]

This PR adds a workflow to run actions/labeler to automatically label PRs based on touched file paths.

This action is already used by Uhyve: uhyve/.github/labeler.yml.

The current labels in this PR are just a gut feeling. It would be great to have your feedback on them and on whether we should do this at all.
