scripts/format: add a command to apply clang-format

problem: we have to remember how to apply clang-format

solution: add to format script

ci: add clang-format to check-format and enforce

problem: we don't automatically check c/c++ formatting on push

solution: add clang-format to the check-format script

I also renamed "python formatting" to "code formatting" here so that
would stay accurate
