Create mxdev sources and checkouts

[thet]

Add scripts to create mxdev compatible ini files from sources.cfg and checkouts.cfg.

This feature is useful with the mxdev include feature, available since mxdev 3.1.0 and done at the Kitchen Sprint 2023 in Völs. See: https://github.com/mxstack/mxdev/pull/37

TODO

• [x] integrate it in tox release workflow.
• [ ] document somewhere
• [x] test a with mxdev

BTW, do you and @jensens indeed prefer to split the sources and checkouts in two files? I would be fine with either one or two files, but two files make it a bit easier to translate between our current buildout config and mxdev, so I would be happy with that approach. A short checkouts.ini makes it easier to see which packages are checked out.

BTW, several commands already work on both buildout and mxdev files. If you temporarily rename or copy checkouts.ini to mxdev.ini, you get this:

$ bin/manage check-checkout Products.CMFPlone
YES, your package Products.CMFPlone is on auto checkout in mxdev.ini.
YES, your package Products.CMFPlone is on auto checkout in checkouts.cfg.

I think having 3 files has it advantages.

• mx.ini over all setup
• mxsources.ini (yes prefix, so it stands together)
• mxcheckout.ini with only the checkouts.

This way one may use only sources with own checkouts/branches(think PLIPS) overrides.
