feat(physics): simple and phantom physics objects register as movement blockers

Browse Source 
A fixed simple physics object, or a phantom volume, that its data marks as a
wall for enemies (a navmesh carver, or solid with a group only enemies touch)
adds its shape to the world's movement blockers, and takes it out again when it
goes away. Only shapes the server knows are used; an unknown asset's stand in
cube would be a guess, so it is logged and left out.
