Keyboard: Add support for the KBD4x (#4036)

Browse Source 
* Generate a new project for the KBD4x

* Specify the possible layouts for the KBD4x - MIT and grid

* Fill out the readme for the KBD4x

* Configure the default keymap and wiring configuration as specified on http://qmkeyboard.cn/

* Add info.json for QMK Configurator

* Enable backlight support for the KBD4x

* Standardise on LAYOUT_planck_mit/LAYOUT_ortho_4x12 layout names

* Add whitespace so the Readme will render correctly

* Disable mouse keys support for the KBD4x to make the firmware small enough
