QMK CLI and JSON keymap support (#6176)

* Script to generate keymap.c from JSON file.

* Support for keymap.json

* Add a warning about the keymap.c getting overwritten.

* Fix keymap generating

* Install the python deps

* Flesh out more of the python environment

* Remove defunct json2keymap

* Style everything with yapf

* Polish up python support

* Hide json keymap.c into the .build dir

* Polish up qmk-compile-json

* Make milc work with positional arguments

* Fix a couple small things

* Fix some errors and make the CLI more understandable
