refactor: unified stm32CubeProg shell script

For Windows it is called using the busybox.
It fixes issues with options parameters not properly parsed
on windows. In batch, options with equal was splitted in 2 args
as the equal was removed:
ex: -ob nBOOT0=0 was passed as -ob nBOOT0 0

ShellCheck and shfmt passed.
