SkyratBot 3fa98bd2cc [MIRROR] Adds UPSIDE_DOWN movetype for negative gravity / makes Atrocinator affected by less things [MDB IGNORE] (#25155) 
* Adds `UPSIDE_DOWN` movetype for negative gravity / makes Atrocinator affected by less things (#79785)

## About The Pull Request

Fixes #79764

I was going to tackle this issue by slamming `TRAIT_NO_SLIP_ALL` on
Atrocinator users and calling it a day, but like, that didn't feel
proper.

So I thought hey, we could just give them the flying movetype, even
though they technically aren't flying it means they're unaffected by
things that flying would make you unaffected by.

Nope, this means the mob technically "negates gravity", so no falling
and no feetsteps.

Let's try floating - this give us feetsteps but no falling upwards.

So instead of going back to square one, with `TRAIT_NO_SLIP_ALL`, I
decided to go for the more complex route of just adding a movetype.

Hence, move type `UPSIDE_DOWN`. This covers situations where a mob would
be "floating" above the ground, but still walking. ...Negative gravity.

This means overall the Atrociator acts more as you'd expect - you don't
slip on ice, you don't trigger bear traps or mouse traps, you can walk
over railings, unaffected by conveyor belts, etc.

## Why It's Good For The Game

Makes the Atrocinator a lot more consistent with how you'd expect for it
to work.

Admittedly it is a bit niche use of movetypes, but it can possibly be
expanded to more things in the future, who knows? I applied it to mobs
on meat spikes (even though they don't move), just for proof of concept.

## Changelog

🆑 Melbert
fix: Atrocinating mobs will now behave more as you'd expect. Meaning
they don't slip on wet patches, can't trigger bear traps / landmines /
mouse traps, ignore conveyors, and can walk over tables and railings.
fix: Floating mobs are unaffected by conveyor belts, acid (on the
ground), glass tables
fix: Floating mobs won't squish stuff like roaches anymore
fix: Fixes bear traps triggering on floating / flying mobs
