More Gun Mod Upgrades

Features "Gun Mods can override cycle recoil and more robustly change ammo type"

Purpose of change

more changes focused for #54723

Gun conversions (since they are barely used) don't have a lot of new gun system stuff.

Specifically I needed to be able to overload the min cycle recoil,
and
I needed to be able to have a default ammo (for UI purposes) that isn't a default ammo available in the default mag of the gun. Without this if you have a gun that takes multiple mag types with different ammo types and then the convert it to fire a different ammo type than the ammo of the first mag it nulls out.

Describe the solution

Revived some commented out code for magazine_default to let it consider conversions. This was already there and commented out in the function def. So I set the default to false (since the rest of the calls don't need it so it would be wasted execution). And in the relevant call set it to true.

Added a new mod entry for overwrite_min_cycle_recoil and a helper for items to take the guns cycle recoil or a mod if there is one.
