Standalone builds for Linux aarch64 (aka arm64)

GitHub released public runners.¹  This will ultimately let us use
standalone installation archives in our linux/arm64 Docker images.²

Changes to the standalone installer to follow separately³, as those need
to be held for merge until after the first release with these builds
available.
