[Core] Add support for RISC-V builds and GD32VF103 MCU (#12508)
* Add support for RISC-V builds and GD32VF103 MCU

* Add toolchain selection in chibios.mk based on the mcu selected in
mcu_selection.mk
* Reorder and added comments to chibios.mk to have a streamlined makefile
* Add GD32VF103 mcu to possible targets for QMK.
* Add STM32 compatibility for GD32VF103 MCU, this is hacky but more efficent
  then rewriting every driver.
* Add GigaDevice DFU bootloader as flash target, please note that
  dfu-util of at least version 0.10 is needed.
* Add analog driver compatibility
* Add apa102 bitbang driver compatibility
* Add ws2812 bitbang driver compatibility
* Add eeprom in flash emulation compatibility
* Allow faster re-builds with ccache

* Add SiPeed Longan Nano to platform files

* Add SiPeed Longan Nano Onekeys

* Make quine compatible with other bootloaders

* Support builds with picolibc

* Add risc-v toolchain to arch and debian/ubuntu scripts

# Compatible Microcontrollers
QMK runs on any USB-capable AVR or ARM microcontroller with enough flash space - generally 32kB or more, though it will *just* squeeze into 16kB with most features disabled.
## Atmel AVR
The following use [LUFA](https://www.fourwalledcubicle.com/LUFA.php) as the USB stack:
* [ATmega16U2](https://www.microchip.com/wwwproducts/en/ATmega16U2) / [ATmega32U2](https://www.microchip.com/wwwproducts/en/ATmega32U2)
* [ATmega16U4](https://www.microchip.com/wwwproducts/en/ATmega16U4) / [ATmega32U4](https://www.microchip.com/wwwproducts/en/ATmega32U4)
* [AT90USB64](https://www.microchip.com/wwwproducts/en/AT90USB646) / [AT90USB128](https://www.microchip.com/wwwproducts/en/AT90USB1286)
* [AT90USB162](https://www.microchip.com/wwwproducts/en/AT90USB162)
Certain MCUs which do not have native USB will use [V-USB](https://www.obdev.at/products/vusb/index.html) instead:
* [ATmega32A](https://www.microchip.com/wwwproducts/en/ATmega32A)
* [ATmega328P](https://www.microchip.com/wwwproducts/en/ATmega328P)
* [ATmega328](https://www.microchip.com/wwwproducts/en/ATmega328)
## ARM
You can also use any ARM chip with USB that [ChibiOS](https://www.chibios.org) supports. Most have plenty of flash. Known to work are:
### STMicroelectronics (STM32)
* [STM32F0x2](https://www.st.com/en/microcontrollers-microprocessors/stm32f0x2.html)
* [STM32F103](https://www.st.com/en/microcontrollers-microprocessors/stm32f103.html)

## Atmel ATSAM
There is limited support for one of Atmel's ATSAM microcontrollers, that being the [ATSAMD51J18A](https://www.microchip.com/wwwproducts/en/ATSAMD51J18A) used by the [Massdrop keyboards](https://github.com/qmk/qmk_firmware/tree/master/keyboards/massdrop).
## RISC-V
### GigaDevice
[ChibiOS-Contrib](https://github.com/ChibiOS/ChibiOS-Contrib) has support for the GigaDevice [GD32VF103 series](https://www.gigadevice.com/products/microcontrollers/gd32/risc-v/mainstream-line/gd32vf103-series/) microcontrollers and provides configurations for the [SiPeed Longan Nano](https://longan.sipeed.com/en/) development board that uses this microcontroller. It is largely pin and feature compatible with STM32F103 and STM32F303 microcontrollers.
