Improve a number of things about how MILC operates (#7344)
* Pull in updates for MILC * Remove the shadow argparser * Make it easier to reason about arguments and how they're translated into the config tree * Populate self.config during init to support setting user.qmk_home for the global CLI * Remove the short argument -c so that we can unambiguously determine the config file location without doing full argument processing * Remove the --save-config option as it's a little confusing anyway * Use Pathlib for path manipulation * Fix commands with no arguments
