typified character.h + npc.h

[PatrikLundell]

Summary

None

Purpose of change

Change usage of untyped coordinates into typed ones. This time character.h and npc.h, plus dependents.

Describe the solution

Replace the untyped coordinated with the appropriate typed ones, as well as the usages. This time there wasn't any need to retain any old operation and create any overload. Removed a few orphaned untyped overloads.

Describe alternatives you've considered

Testing

There's no functional change, so no particular thing to test.
Loaded save, walked up ramp, jumped into car, drove through hay stacks, ran over zombie corpse with inventory, ran into, but failed to run over, some turkeys, smashed into stationary vehicle. Nothing odd noticed.

Additional context

The next pass will include character.cpp and npc.cpp. We'll see if there's room for something else after that.
