Physics (#3485)

* Content side new physics structure

* BroadPhase outline done

* But we need to fix WorldAABB

* Fix static pvs AABB

* Fix import

* Rando fixes

* B is for balloon

* Change human mob hitbox to circle

* Decent movement

* Start adding friction to player controller

I think it's the best way to go about it to keep other objects somewhat consistent for physics.

* This baby can fit so many physics bugs in it.

* Slight mob mover optimisations.

* Player mover kinda works okay.

* Beginnings of testbed

* More testbed

* Circlestack bed

* Namespaces

* BB fixes

* Pull WorldAABB

* Joint pulling

* Semi-decent movement I guess.

* Pulling better

* Bullet controller + old movement

* im too dumb for this shit

* Use kinematic mob controller again

It's probably for the best TBH

* Stashed shitcode

* Remove SlipController

* In which movement code is entirely refactored

* Singularity fix

* Fix ApplyLinearImpulse

* MoveRelay fix

* Fix door collisions

* Disable subfloor collisions

Saves on broadphase a fair bit

* Re-implement ClimbController

* Zumzum's pressure

* Laggy item throwing

* Minor atmos change

* Some caching

* Optimise controllers

* Optimise CollideWith to hell and back

* Re-do throwing and tile friction

* Landing too

* Optimise controllers

* Move CCVars and other stuff swept is beautiful

* Cleanup a bunch of controllers

* Fix shooting and high pressure movement controller

* Flashing improvements

* Stuff and things

* Combat collisions

* Combat mode collisions

* Pulling distance joint again

* Cleanup physics interfaces

* More like scuffedularity

* Shit's fucked

* Haha tests go green

* Bigmoneycrab

* Fix dupe pulling

* Zumzum's based fix

* Don't run tile friction for non-predicted bodies

* Experimental pulling improvement

* Everything's a poly now

* Optimise AI region debugging a bit

Could still be better but should improve default performance a LOT

* Mover no updater

* Crazy kinematic body idea

* Good collisions

* KinematicController

* Fix aghost

* Throwing refactor

* Pushing cleanup

* Fix throwing and footstep sounds

* Frametime in ICollideBehavior

* Fix stuff

* Actually fix weightlessness

* Optimise collision behaviors a lot

* Make open lockers still collide with walls

* powwweeerrrrr

* Merge master proper

* AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

* AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

* AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

* Ch ch ch changesss

* SHIP IT

* Fix #if DEBUG

* Fix vaulting and item locker collision

* Fix throwing

* Editing yaml by hand what can go wrong

* on

* Last yaml fixes

* Okay now it's fixed

* Linter
