Subject: Add rules.mk defaults for f103,f072,f042 (#7704)

* Add rules.mk defaults for f103,f072,f042

* Add rules.mk defaults for f103,f072,f042 - remove comment

* Add rules.mk defaults for f103,f072,f042 - align USE_FPU

* Reset MCU to avoid build issues

* Move essential config values to top and remove ability for override

* Align DFU_SUFFIX_ARGS order with DFU_ARGS
