Deprecate the can_attach_workq() API call. This API is limited in its functionality (it does not work with userspace, it uses one common buffer size for all work queue instances). Similar functionality can easily be implemented using the can_attach_msgq() API along with the generic triggered work API (e.g. using k_work_poll_submit()).

Do not mess with it unless you know what you are doing.
