feat(users/flokli/kb): add chocofi r/8922

`buildSplitKeyboard`, as well as all the patching of `miryoku_zmk` is
independent of the specific keyboard used, so it can be moved one layer
up.

`config-flat` is now provided through a helper function, accepting the
name of the keymap to use when rendering the config.

This all makes the amount of code added for the new keyboard itself
pleasantly small.
