Python 2 standard library had platform specific modules like CDROM which were generated by Tools/scripts/h2py.py. These modules were removed, but h2py.py is still around.

There are now way better ways to expose C APIs in Python like cffi.

I propose to simply remove Tools/scripts/h2py.py.

Attached PR removes the file and update files which mention it. It would allow to simply close bpo-13032.

Issue bpo-28027: Remove [Lib/plat](https://github.com/python/cpython/blob/main/Lib/plat)-* files

Python 2 standard library had platform specific modules like CDROM which were generated by Tools/scripts/h2py.py. These modules were removed, but h2py.py is still around.

Example of Python 2.7:

$ head -n1 Lib/plat-linux2/IN.py 
# Generated by h2py from /usr/include/netinet/in.h
...

$ tail -n1 Lib/plat-linux2/regen 
...
h2py -i '(u_long)' /usr/include/sys/types.h /usr/include/netinet/in.h /usr/include/dlfcn.h
