Followup to #18138

- Now compiles and works correctly with changes to HAL timers and watchdog.
- Does NOT include awesome work on touch screen function.
- Does have working LCD and SD-based EEPROM.

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).
