[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 as the USB stack:

Certain MCUs which do not have native USB will use V-USB instead:

ARM

You can also use any ARM chip with USB that ChibiOS supports. Most have plenty of flash. Known to work are:

STMicroelectronics (STM32)

NXP (Kinetis)

Atmel ATSAM

There is limited support for one of Atmel's ATSAM microcontrollers, that being the ATSAMD51J18A used by the Massdrop keyboards.

RISC-V

GigaDevice

ChibiOS-Contrib has support for the GigaDevice GD32VF103 series microcontrollers and provides configurations for the SiPeed Longan Nano development board that uses this microcontroller. It is largely pin and feature compatible with STM32F103 and STM32F303 microcontrollers.
