Docker multiarch image

[eternal-flame-AD]

fixes #257 . fixes #350

Simply make build-docker-multiarch and then docker run should work. I implemented building JS from docker as well but opt-in, just for people who want's to build a usable local container without having to do anything outside of docker.

Current blockers: (nevermind I had a nap and figured out how to do it)

The last step of installing runtime dependency need qemu, it's not easy to get around that unfortunately

Here's the Docker scout cloud analysis, you should be able to reproduce it with docker scout CLI.

Sorry about the force pushes, messed up a rebase :(
