Subject: [PATCH] Add release binaries for FreeBSD / OpenBSD

This adds support for both FreeBSD and OpenBSD with both amd64 and
arm64 architectures, consistent with our existing Darwin/Linux binaries.

Note that this still needs updates in our NPM release process to fully
resolve the linked issue.

Related to #3047.
