typified a bit of map.h/cpp + dependents

[PatrikLundell]

Summary

None

Purpose of change

• Continue the quest to use typed coordinates rather than untyped ones.
• Fix map::process_fields_in_submap is probably bugged #76336, bugged handling of map::process_fields_in_submap. The report was closed prematurely when the functional bug was fixed, but the incorrect type usage remained.
• Fixed one place where typification revealed that an absolute coordinate was used as a bubble parameter. Changed that instance to convert the coordinate to a bubble one before usage, as was done in a similar call on the next line.

Describe the solution

• Find usages of untyped map operations and convert them to usages of the corresponding typed one.
• Remove the untyped operation if all usages had been converted.
• getabs was processed, and it could finally be removed completely (in favor of getglobal, which returns a typed value).

Describe alternatives you've considered

Testing

Loaded a save, walked up a ramp, sat in a car, drove it through some hay bales, over some corpses (and their stuff), and hitting some random birds. Nothing weird seen.
Apart from the corrected call, there should be no functional changes. Unfortunately, I don't know how to test that change, but it can't have been vitally important, as it doesn't seem to have resulted in any visible errors.

Additional context

The going is slow... about 60 lines of map.h, out of over 3000. We're going to have to eat this elephant for a long while.
