System status action. The status action is invoked whenever a system is enabled or disabled. Note that a system may be enabled but may not actually match any entities. In this case the system is enabled but not active.
In addition to communicating the enabled / disabled status, the action also communicates changes in the activation status of the system. A system becomes active when it has one or more matching entities, and becomes inactive when it no longer matches any entities.
A system switches between enabled and disabled when an application invokes the ecs_enable operation with a state different from the state of the system, for example the system is disabled, and ecs_enable is invoked with enabled: true.
