stagex refactor

[lrvick]

Highlights

• git lfs artifacts removed
• toolchain removed
• make flow dramatically simplified. Single file.
• all actual build steps now handled in overhauled containerfiles in src/images
• make: deterministically build all the things with stagex build container
• make test: run all tests in build container
• make lint: run automated linting from build container
  • disabled as current code does not pass linting
• make format: run rustfmt from build container
• make docs: run rustdocs from build container
• make gen: run "make -C proto" under stagex with stagex-provided tools
• CI refactored to use all of the above exactly as you would locally

Doesn't this change the directory for the following touch command as well?

Suggested change

	cd out/build-base; \
	tar -cf - . | docker load
	(cd out/build-base; tar -cf - . | docker load)

or can you use the the -C argument to tar?

-C, --directory=DIR
              Change to DIR before performing any operations.  This option is order-sensitive, i.e. it affects all options that follow.

Macs dont have -C sadly. that is why I remove -C

I know mac env doesn't have -C but I thought their tar would.
