Show coordinates of point entities such as info_teleport_destination in the entity properties

Originally requested from Bocuma:

Brush entities have their origin coordinates listed here but point entities don't, which means I have to open the vmf in a text editor to find it.

This will have the caveat of the sphere helper showing for point entities:

Isn't info_teleport_destination depreciated?

[TeamSpen210]

"Deprecated" yes, but that's sorta pointless, it's just a base class entity with nothing special.

deprecated in the sense that they're not strictly required for anything and you can just use info_target instead yes, but 99% of maps still use them for either a sense of scale, organization, or purely out of habit so we're going to continue supporting it.
