Keyboard: Improvement of crkbd communication functions (based on helix-keyboard) (#3798)

Browse Source 
* improvement of crkbd communication functions (based on  helix-keyboard)

* Removed unnecessary code.

* Changed read restriction from #define to #pragma once.

* Changed from sizeof to defined size.

* moved lib folder to crkbdroot.
removed warning of ws2812.d
