build: add arm64 tools build (genpolicy, agent-ctl, kata-ctl, etc.)

The arm64 build workflow was missing the tools build entirely.
Add build-tools-asset and create-kata-tools-tarball jobs mirroring
the amd64 workflow so that genpolicy and the other tools are
available for coco-dev tests that need auto-generated policy.
