Port /tg/ move manager, drift and jetpack components. (#27698)

* Port /tg/ move manager, drift and jetpack components.

* don't add go through newtonian movement if not moved to a turf

* various cleans for blood drifts and mob speed

* fix slow meteors

* why on fuck's earth aren't speedbikes vehicles

* style lint

* also wtf

* okay i'm an idiot

* fix meaty ore speed and blood decal double stepping

* fix not unbuckling pulled object occupants

* don't bother dealing with immovable rods just yet

* exclude bubblegum and vetus from move manager for now

* fix issues related to null weightless blood icons

* reset blood icon state properly

* fuck it, we'll deal with mobs when basic mobs happen

* break infinite loop in decal splat
