A comprehensive refactor / cleanup of bullet_hit and on_hit to cut out a single bad species / mob proc (#79024)

## About The Pull Request

- Refactored `bullet_act`. Adds `should_call_parent` and refactors
associated children to support that.
   - Fixes silicons sparking off when hit by disabler fire. 
- Desnowflakes firing range target integrity and cleans up its
bullet-hole code a bit.
- Cleans up changeling tentacle code a fair bit and fixes it not taking
off throw mode if you fail to catch something.
   - The Sleeping Carp deflection is now signalized 
- Nightmare projectile dodging is now signalized and sourced from the
Nightmare's brain rather than species
- Refactored how cardboard cutouts get knocked over to be less
snowflaked / use integrity
- Also adds projectile `on_hit` `should_call_parent` and cleans up a bit
of that, particularly their arguments.
- On hit arguments were passed wrong this entire time, it's a good thing
nothing relied on that.

## Why It's Good For The Game

This is cringe.

Bullets should overall act more consistent across mob types and objects.
