Add "source component" to dev-state panel

So, I have a few different hubs and components that bring in items with similar (if not the same) names. Sometimes I can prevent this with a little thought, but sometimes I can’t… when this happens troubleshooting and figuring out which component spawned a particular entity can be a bit painful. I would love to see the name of the component that generated an entity be added to the dev-state card.

Would additionally unlock the ability to use things like the Lovelace entity cards to be able to group entities by their component - which for me could be very handy.
