* 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
