Add a workflow for linting and add a cppcheck job.
The job is using cppcheck provided by package manager. Existing errors
are suppressed to get going with CI linting, ideally tho the suppression
list would be empty. Some of the suppressed errors are only found with
more recent cppcheck than what is available in the runner.
Also remove old arclint cppcheck setup.
