Investigate removing CollisionWake

[metalgearsloth]

It's an artifact from when every single item entity being on the dynamictree made the game unplayable.

It might be better these days but having to manually bookkeep it is somewhat annoying and leads to having to work around it for stuff like conveyors or grid overlap for example.

StaticSundries tree probably needs to remain (e.g. for subfloor anchored entities or w/e) but I think we could re-benchmark rolling SundriesTree into DynamicTree.
