This moves all the release builds into a Dockerfile which is a bit cleaner for setting up our build environment. Non-linux/amd64 builds are cross-compiled. Currently onlinux linux/amd64, linux/arm64, and windows/amd64 are supported, but is easy to add more, provided their is a cross-compile toolchain available for it.
