[C++] [lua] Implement Automaton Equalizer

• I understand I should leave resolving conversations to the LandSandBoat team so that reviewers won't miss what was said.
• I have read and understood the Contributing Guide and the Code of Conduct.
• I have tested my code and the things my code has changed since the last commit in the PR and will test after any later commits.

What does this pull request do?

• Implements the automaton attachment equalizer. It's a bit of a weird attachment, but it generates a damage reduction value(for physical damage) based on the amount of max HP you have, and the size of the hit - making it most effective when you're using a low HP automaton (like a mage type) and taking a very large hit. The damage reduction it can provide is capped at 90%. I was having trouble getting the damage reduction just right, but discovered adding a floor to damage reduction after its calculated results in a 100% accurate damage reduction when compared to retail.

• Fixes a bug I created with the trait Stout Servant when I moved automaton mods to lua, now uses "addMod" instead of "setMod" so that they stack correctly, this should be completely safe as every newly created automaton is a dynamic entity.

Steps to test these changes

Equip Equalizer, use Earth Maneuvers, see it reduce really high damage abilities by a lot (try something like Death Scissors)
