kuksa-dbc-feeder: add recipe and dependencies

Add a kuksa-dbc-feeder recipe to build the sample CAN feeder for the
KUKSA.val Vehicle Information Service (VIS) server and add it to the
agl-demo-platform image by adding it to packagegroup-agl-ivi-services.
Local patches are applied to enable building with OpenEmbedded, make
installation into standard Linux FHS locations feasible, and improve
usability on target with respect to logging and error handling.
These will be discussed with upstream to hopefully get them
integrated.

Additional changes:
- Add a recipe for the required kuksa-viss-client Python module
  included with the KUKSA.val source tree.  The module is also
  available via pypi.org, but keeping all the pieces in lockstep for
  now seems better, so it is built out of a clone of the kuksa.val
  repo using the same SRCREV as the server and kuksa-dbc-feeder.
- Add new recipes for required Python modules:
    python3-argparse-addons, python3-can-j1939,
    python3-py-expression-eval, python3-setuptools-git-versioning
  These will be upstreamed to meta-python as time permits.
- Add bbappend for python3-cantools to add a missing runtime
  dependencies discovered during testing.  This will be addressed
  upstream in meta-python as time permits.
- Add minimal DBC file and mapping configuration.  At present the
  agl-vcar.dbc file only contains the minimum message definitions
  known to be required for the AGL demo platform, namely vehicle
  and engine speeds and the steering wheel events.
- Add can-dev-helper recipe to install a systemd unit and script to
  ensure a CAN interface is available for testing.  This is a tweaked
  version of what was previously used with agl-service-can-low-level.
