Add support for MKS Robin board (#12650)
Implement initial support for MKS Robin (STM32F103ZET6) board. Custom build script is used to generate encrypted firmware compatible with original MSK Robin bootloader (i.e. safe firmware update from SD card and possibility to go back to original close-source firmware).2.0.x
