Subject: [PATCH] Add atmos link override variables to hand teleporters and
 portal guns (#39641)

Portals have supported atmospherics linking for a long time, just that it
defaults to off. This would allow admins to let the two things that uses basic
portals (not wormholes) enable it for portals they create.
