Refactor f103,f072,f042 based keyboards to use new MCU selection defaults (#7705)

* refactor keyboards using ST_STM32F072B_DISCOVERY to use 'MCU = STM32F072'

* refactor keyboards using GENERIC_STM32_F042X6 to use 'MCU = STM32F042'

* refactor keyboards using GENERIC_STM32_F103 to use 'MCU = STM32F103'
