fix totally broken guns pulled off of turrets yielding intact guns

[misterprimus]

Summary

SUMMARY: Bugfixes "Fix broken gun fixtures on vehicles spawning intact guns when uninstalled"

Purpose of change

To remove exploit that allows guns to be repaired during the removal process. Fixes #37618

Describe the solution

Replaces the "breaks_into" line of the turret.json file with "scrap" instead of [gun]. Now you get scrap metal when you uninstalled a totally smashed gun from a turret, as you should.

Describe alternatives you've considered

Testing

Uninstalled intact, damaged, and destroyed guns from gunship. Result was always as expected.

Additional context

[Brian-Otten]

The one thing that might still need to happen here is make them all break apart into the correct portions of scrap, rather than all of them giving 1-4 scrap metal. If you don't want to do the work for that this could probably be merged and that posted up as a separate issue.

Although they have quite a range of volumes and weights, these guns tend to be fairly large and heavy, ex.:

• G80 railgun: 2.75 L, 3.91 kg
• M134D-H minigun: 6.0 L, 19.77 kg
• M2HB Browning HMG: 5.0 L, 38.0 kg

"Scrap metal" is relatively small and lightweight in-game (0.03 L, 0.05 kg). Even a completely slagged M2HB should give a lot more than 200g of raw metal.

In addition to yielding scrap, it seems appropriate for these broken guns to yield a few possible steel_chunk (0.07 L, 0.25 kg) and/or steel_lump (0.13 L, 1.0 kg) as well.

True I think I'll throw it into an excel table and make up the parts that way.
