carlfriedrich eedf3ae890 Meta: Add GitHub release action
The action is executed on every tag and creates a GitHub release. The
release contains a .tar.gz asset and a changelog consisting of all
commit messages since the previous tag. Commits with a commit message
starting with "Meta" are excluded from the changelog.
