Use docker compose

[patrick-5546]

Description

Make the dev container use docker compose. Previously, it was built on .devcontainer/Dockerfile. Now it is built on .devcontainer/docker-compose.yml, which builds the dockerfile. Using docker compose allows the dev container to run multiple images.

Verification

• Rebuild dev container locally

@hhenry01 FYI see the first commit. We previously discussed that the dev container doesn't need to see CAN, as the mocks won't be using VCAN.

Overall plan is to refactor #107 into multiple smaller PRs, the first of which is this one.
