devlink: Add support for direct reporter health state update
It is possible that a reporter state will be updated due to a recover flow which is not triggered by a devlink health related operation, but as a side effect of some other operation in the system. Expose devlink health API for a direct update of a reporter status. Move devlink_health_reporter_state enum definition to devlink.h so it could be used from drivers as a parameter of devlink_health_reporter_state_update. In addition, add trace_devlink_health_reporter_state_update to provide user notification for reporter state change.
