Add support to serialize btOptimizedBvh/btQuantizedBvh for a btBvhTriangleMeshShape (using the new btSerializer). This is a new implementation, with full cross-platform support.

So it is different from the in-place method (btQuantizedBvh::serializeInPlace/deserializeInPlace).

It is also possible to serialize/deserialize just the bvh, using the btSerializer (needs some code snippet/helper)
