Implement raise/lower for default keymap.

* Properly allow includes for keymaps to allow defining
  custom keycodes, and then adding them to the
  keymap.overlay file.
* Fix keymap.c loading after build refactor.
* Fix for deactivating a layer working properly.
* Fix default keymap to put transparent in proper spots to
  make raise/lower keycodes work as expected.
* Add custom raise/lower keycode handling to default
  keymap.
