Add range visualization for artillery turret prototypes

[calcwizard]

When holding or selecting most turrets, it renders the range of the turret on the screen. However, this is not the case for artillery turrets. While this is understandable given the range of the vanilla artillery turret, I would like to add this functionality to modded turrets. While entities have a way to do this generically with radius_visualisation_specification, the radius of that is fixed and doesn't change as range is upgraded.

As such, I'm requesting a property for an artillery turret prototype to allow turret range visualization. Alternatively, the ability to resize the radius_visualisation_specification during control.

Thanks.
