Entry Point of the official Marlin firmware for Kobra Go

[xiaopeng12138]

This is the entry point of the hc32f460
https://github.com/ANYCUBIC-3D/Kobra_Go/blob/e675180de25a622936be74ddf364f59715ec3943/source/app/main.cpp

Most custom stuffs are in the source/board folder. Maybe someone can find more interesting things.
hc32f460 is a quiet powerful mcu, add some additional function should not be hard
