Targeting Datums Renamed (and global) (#79513)

## About The Pull Request

[Implements the backend required to make targeting datums
global](6901ead12e)

It's inconsistent with the rest of basic ai for these to have a high
degree of state, plus like, such a waste yaknow?

[Implements
GET_TARGETING_STRATEGY](d79c29134d)

Regexes used:
new.*(/datum/targetting_datum[^,(]*)\(*\)* -> GET_TARGETING_STRATEGY($1)

Renamed all instances of targetting to targeting (also targetting datum
-> targeting strategy)

I've used GET_TARGETING_STRATEGY at the source where the keys are
actually used, rather then in the listing. This works out just fine.

## Why It's Good For The Game

Not a misspelled name through the whole codebase, very slightly less
memory load for basically no downside (slight cpu cost maybe but not a
significant one.
