[PATCH v2 0/2] add basic b4 config file

[Quentin Schulz <foss+yocto@0leil.net>]

This adds very basic support for using b4 in OE-Core. This essentially
just automatically adds the proper mailing list when running b4 prep
--auto-to-cc.

This also adds the b4 wrapper script that poky will need to use in order
to identify which mailing list a patch needs to be sent to and do some
additional per-patch checks that aren't necessary when running from
vanilla OE-Core.

Once this is merged, poky will need to merge OE-Core into itself and
override with its own .b4-config that makes use of that script.

Changes in v2:
- add mention to first patch that running patchtest for b4 prep --check
  is what we're eventually aiming for,
- add poky b4 wrapper script (it used to be in the patch series for
  poky, c.f. https://lore.kernel.org/poky/20250123-b4-support-v1-1-4841f52eccbb@cherry.de/T/#m95d6aa25cc42352416da477cf07d7b3cbd671231
- poky b4 wrapper script properly identifies patches with files modified
  in both OE-Core and other repos part of poky,
- poky b4 wrapper script pretty prints when there's more than one
  project modified by a script, instead of lazily printing a Python
  list,
