Use GitHub Actions and delete Travis / AppVeyor configuration

[tniessen]

Some internal discussion suggests that we should migrate all organization repositories to GitHub Actions. As far as I am aware, this is the only remaining repository in the Node.js organization that has a Travis configuration.

This issue is not a duplicate of but likely supercedes #508.

Yes, please. Travis has not worked for years and AppVeyor is slow. I presume Windows testing is available as well. I have never used Github Actions.

Yes. Currently, the list of supported platforms through GitHub-hosted runners includes ubuntu-22.04, ubuntu-20.04, windows-2022, windows-2019, macos-13, macos-12, and macos-11. We typically run tests using the aliases ubuntu-latest, windows-latest, and macos-latest so that we don't need to update any configuration as GitHub upgrades their platforms.
