Fix #3827: Vehicles passing through frozen objects

[iManGaaX]

Summary

The frozen state set bDisableCollisionForce but not bCollidable, so vehicles ignored frozen objects entirely; apply the same flag combination GTA uses for immovable objects and restore it on unfreeze

Closes #3827.

Example:

local x, y, z = getElementPosition(localPlayer)
local o = createObject(1491, x + 3, y + 3, z - 1)
setElementFrozen(o, true)
