Add more common hardware interface type constants

[saikishor]

This is to add more sets of more common hardware interface type constants that are used day-to-day. Defining it here would bring some standards in the naming + reusability.

I'm not entirely sure at this part, then it means we have to update the ros2_controllers to have a parameter to accept the effort type, and by default it stays with the EFFORT and users can configure it. This would be the next task
