scripts/libc_posix.py seems great. Can we expand its scope? #6628

So the way that the script works is by parsing the documentation of the os module and extracting every word that is comprised from only uppercase letters. So for modules like _locale, there's no public documentation (but there's for locale). So we can expand it, yes. but I think it would be better if we make it so the script will output the generated code to a separate file and we will include!(...) it, if we are planning on supporting more than one module with that script.

Also, I suggest to move those scripts to a dedicated folder called tools as we have multiple scripts that are becoming more and more standalone tools
