config: Anycubic Vyper (#4740)

This commit contains a configuration for the Anycubic Vyper printer from 2021.
It uses a clone of the STM32F103 chip named GD32F103.
There are 2 Mainboard versions out there v0.0.5 and v0.0.6, this config has
been tested with the v0.0.6 only. It should probably work for v0.0.5 as well
since there are no different changes in the Anycubic Marlin firmware.
The LCD is not supported yet (might work, but didn't try yet).

+# This file contains a configuration for the Anycubic Vyper printer from 2021.
+# It uses a clone of the STM32F103 chip named GD32F103.
+# There are 2 Mainboard versions out there v0.0.5 and v0.0.6, this config has
+# been tested with the v0.0.6 only. It should probably work for v0.0.5 as well
+# since there are no different changes in the Anycubic Marlin firmware.
+# The LCD is not supported yet (might work, but didn't try yet).
+#
+# To create the Firmware you need to use the following configuration:
+#     - Micro-controller: STM32
+#     - Processor model: STM32F103
+#     - Bootloader offset: 32KiB
+#     - Communication interface: Serial (on USART1 PA10/PA9)
+#
+# To install the Firmware rename the klipper bin to `main_board_20xxxxxx.bin`
+# and copy it to an SD Card.
+# Power off the Printer, insert the SD Card and power it on.
+# It should beep several times and the LCD should be stuck on the Splash screen.
+# Now you should be able to connect to the Printer, you might need to change
+# the mcu/serial setting in this config according to your set up.
+#
+# If you want to revert the Firmware back to Marlin you simply need to flash it
+# with a anycubic firmware through the SD Card
