Use this feature to retrieve only Glide vehicles, not all server entities

[Vitroze]

It's better to use the glide function, which retrieves only glide vehicles, rather than retrieving all entities on the server.

Even though this feature is rarely used, it's still a form of micro-optimization.

Do not use Glide.GetAllVehicleEntities on ResetAll. On single-player map changes, the Lua environment is recreated, so the list of vehicles that function is keeping track of is empty.

Technically, the vehicle entities already exists before Lua starts, and handing the quirks that comes from that is why ResetAll exists in single-player on the first place.

Under what circumstances can glide vehicles be present in the PreCleanupMap?

I tried with the original code and my modification, but in my tests, no glide vehicles were present.

Yeah, the EntityRemoved hook runs before PreCleanupMap. Closing this PR for now since we can't use Glide.GetAllVehicleEntities in there, or in ResetAll.
