Initial refactor to have a shield/board have one default keymap.

* Start of work of focusing on out-of-tree user keymaps.

Add ZMK_CONFIG support.

* General external configuration supported via ZMK_CONFIG,
  which should point to a configuration directory.
* Priority order of overlay files to select.
  * ${SHIELD}_${BOARD}.overlay
  * ${SHIELD}.overlay
  * ${BOARD}.overlay
  * default.overlay
* Equivalent search order for .conf files for initial Kconfig
  values.
