* Fix#11570 - create gfx_draw_string_centered() overload
I created the overload, updated all calls from the old function to the new and deleted the old one
A single car on a coaster can comprise of multiple vehicles. One of those vehicles will be the car head vehicle. The train can comprise of multiple cars. Therefore not all vehicle->IsHead 's will be in SPRITE_LIST_TRAIN_HEAD. This rename makes that slightly more clear
* Reduce direct usage of Location_Null
Ideally we want to refactor these out to use std::optional as much as possible but for now move to using the standard interfaces.
* Remove incorrect AND with LOCATION_NULL
In the original this was a simple comparison to check for negative. Unsure how it ended up as an AND with the negative bit.
