[WIP] Initial docker skeleton

[no2chem]

Overview

Description: This PR implements a basic Docker build, which should help eliminate the complexity of the build environment and dependencies. This would allow us to remove the setup script, provide a consistent environment for debugging --- and point users to the builder dockerfile if they wish to run natively. This would also make it easier to support Cascade, as docker should be available on Linux, Windows and macos.

It's a WIP and shouldn't be merged. A few things remain:

• [ ] Parts of Cascade expect to be running in the same machine (for example, sw_fpga). The documentation needs to be rewritten for containers
• [ ] Untested on the DE10. Presumably should work, but I/O and FPGA configuration probably needs to be exposed to the container somehow.
• [ ] Instructions for debugging in the Docker container. vscode and devcontainer support work fairly well, so we should at least document that for those looking to use the container-based environment.

Checklist (Definition of Done):

• [ ] There are no TODOs left in the code
• [ ] Change is covered by automated tests

Closing this request for now.

This sounds valuable long term, but for the short run, I think we're going to focus on compatibility with the standard *NIX environment.

We've made a bunch of changes to setup to ensure that cascade installs correctly to usr/local/. The next steps probably look more like configuring apt-get and brew packages.
