Set `BOOTLOADER = stm32-dfu` for all applicable STM32 boards (#12956)

* Set bootloader to stm32-dfu for STM32F303

* Set bootloader to stm32-dfu for STM32F0x2

* Set bootloader to stm32-dfu for STM32F4x1

* Set bootloader to stm32duino for sowbug

* Delete redundant bootloader_defs headers

* Add some missing MCU name comments

* Move APM32 dfu-suffix overrides underneath bootloader

* Remove redundant STM32_BOOTLOADER_ADDRESS defines/rules
