Add packaging for Linux CPython x86_64

[frodon1]

The packaging was added for CPython x86_64 on Linux, from python 3.7 to python 3.13.
Some porting was added in specific commits for portability to python 3.12 and 3.13.
Additional porting in the build procedure needs to be done for those versions on Windows.

The build mechanism for Linux is based on cibuildwheel.

This PR fixes #1 and #3 on Linux.

@ksmyth any chance you can have a look at my PR ? Thanks !

Thanks for the PR. The Linux .whl looks good as far as I can tell. However, the Windows .whls changed.

1. Could you please modify the build so that these files (and similarly-named) aren't included in the .whl:

omniORB/GNUmakefile
omniORB/GNUmakefile.in
omniORB/dir.mk

2. COS/omniORB.pth contains omniORBCOS on windows, but omniORB/COS on Linux. Perhaps this is a backslash escape character error? But on Windows, the COS directory is installed directly in site-packages, which makes the .pth file unnecessary. So I think the best fix is to exclude this file on Windows.

Please make these changes, then I'll merge the PR.

The corrections were made, the wheels for Windows seem fine now.
Best regards

Looks good, thanks very much.

My pleasure, any idea when the linux wheels will be available on pypi?

[ksmyth]

"linux" wheels are rejected by pypi. The omniORB build has repair-wheel-command = "", which is the step that normally converts "linux" wheels into "manylinux" wheels. I don't know offhand how to make the repair-wheel work.
