Purpose of change

So I belatedly didn't really as deep of a look at #5679 until recently and realized that the item variations are unnecessary, since having a single piece of clothing with the climate control flag will apply the effect to the whole body, not just the parts covered by that item. We can justify only bothering with the torso+arms+legs version providing a full-body effect via it affecting core body temperature, and obsolete the mask and full-body versions instead.

Describe the solution

1. Moved the original full-body cooling outfit and the cooling balaclava to obsolete folder and obsoleted the recipes for them. Also added a JSON comment to the balaclava noting how it might be useful if we make climate control bodypart-specific in the future.
2. Reworded the description for the cooling suit to better explain it affects the entire body.
3. Misc: Fixed a redundant recipe for the thermal cooling outfit very obviously having meant to be a recipe for the thermal cooling suit that was previously overriding the "make a thermal cooling outfit from a thermal outfit" recipe variation.
4. Replaced spawns of thermal cooling outfit in itemgroups with the suit variation.

Describe alternatives you've considered

Flailing at the code to make sources of climate control only affect the bodyparts they cover, which would then require I add thermal cooling gloves and socks to pair with the balaclava, in addition to making sure power armor helmets cool of the head separate from the rest of the armor.

Testing

1. First actually tested before opening this PR to confirm that turning on a cooling balaclava would indeed correct temps for the entire body.
2. Checked affected files for syntax and lint errors.
3. Load-tested in compiled test build.
