BulletSim: default physical terrain implementation to heightmap.

It originally looked like mesh terrain would perform better for vehicles
but, after much use, heightmap is the clear winner.
Force terrain implementation to heightmap if the physics region is
larger than legacy region size. This solves running out of memory for
very large regions.
