rigidbody: Add option to choose mesh source for collision shapes

The options are:
Base: Base mesh
Deform: shape keys and deform modifiers
Final: All deformations and modifiers

It would be nice to have a way of specifying where exactly in the
modifier stack the collision shape is generated. However this is not
staight forward since the rigid body simulation is not part of the
modifier system and would require hacks to make it work.
