Build multi-architecture images (#197)

# What Allows us to push multi-architecture builds for `linux/amd64` and `linux/arm64` on merge to master. Fixes: #196 Tests are performed by building the relevant image and tagging it with the image name the tests expect. This follows the original implementation in `test.sh`. This will likely change to an explicit image name specification as we move the test suite in to Javascript but it's being maintained for now in the interest of simplicity. ## Goals * To decouple image build from the test run. This will help as we refactor the test suite for this issue #191. * Not have CI take a long time due to multi-architecture builds for interim pushes to pull requests. * CI should fail fast if any of the image builds or tests fail * Parallelize builds as much as possible. ## Notes * Since the `unprivileged` and `latest-njs` images build off the base `oss` image, there were some strange moves that had to be done to make that work without rebuilding the base image every time. Specifically, we had to set `setup-buildx-action` to run in `docker` driver mode so we can simply `load` the base image. Otherwise we would have had to use a local repository. However, in `docker` mode `upload-artifact` doesn't like the file produced so we have to save the file again. * I wanted to build images once and then run tests against them and push at the end. However, there was not a clean way to get the full multi-architecture images all the way to the push step so I just build them again against all architectures and perform tests in the runner architecture. This saves us from needing conditionals in the test portions.
