Dynamic BVH doesn't update the tree anymore when calling set_pairable with no parameter change. Also modified Godot Physics broadphase to create objects directly with pairable (static) set correctly to make use of this optimization for the BVH broadphase. Note: Octree broadphase doesn't use this optimization because it forces an update on move, so passing the proper AABB and static parameters on creation would cause the tree to update twice.
