[Keyboard] YMDK NP21: matrix and keymap refactor (#8112)

* YMDK NP21: matrix and keymap refactor

- refactored layout macros
  - LAYOUT_ortho_6x4 orients the keyboard with the USB port to the back instead of to the right
  - LAYOUT uses the previous sideways orientation (included for backwards compatibility)
- removed redundant includes from ymdk_np21.h
- added a readme for the default keymap

* add Configurator layout support
