scripts: stm32cubeprogrammer: Add possibility to flash a bin file

Add the option to flash a bin file if one is available from the board's
cmake configuration.
Use of elf has prio over this, and bin has prio over hex which remains
the default option.
Also add a parameter to stm32cubeprogrammer runner to specify the download
address.
