eeprom_stm32: implement high density wear leveling (#12567)

* eeprom_stm32: implement wear leveling
Update EECONFIG_MAGIC_NUMBER
eeprom_stm32: check emulated eeprom size is large enough
* eeprom_stm32: Increasing simulated EEPROM density on stm32
* Adding utility script to decode emulated eeprom
* Adding unit tests
* Applying qmk cformat changes
* cleaned up flash mocking
* Fix for stm32eeprom_parser.py checking via signature with wrong base
* Fix for nk65 keyboard
