feat(physics): real sizes for the navmesh carvers the server didn't know

Browse Source 
Walls whose asset shape the server doesn't know are left out of the movement
blockers (a stand in cube would be a guess), which left out every navmesh
carver in Robot City (hedges, hedge corners, potted bushes, greebles, robot
statues) and the Ninjago Monastery benches. Their sizes now come from the
client's own collision shapes (res/physics): the bounds of all of a shape's
parts, with the offset of the box from the object's position. The hedge
corner is an L, so its box also covers the inside of the corner.

The same bounds match two shapes the server already had (misc_phys_10x1x5:
10 x 5 x 1; Trigger_Rectangle_Box: 8 x 8 x 4).

CreatePhysicsEntity's shape lookup becomes CreateAssetShape, which needs no
component, for walls without an object.

Still unknown: the Ninjago Monastery cave's primitive model carver (a 77.6
cube whose origin, centre or base, isn't known).
