Subject: [PATCH] CI: Add OpenBSD build tests for staged commits (#1964)

Use a GitHub-hosted VM to create OpenBSD test environment. Requires
GitHub repository configuration that permits the use of
`vmactions/openbsd-vm@v1` Action.

We have not enabled ccache optimization for OpenBSD tests because we
do not know how to copy updated ccache files from VM back into runner.
