BGE Cleanup: Removing KX_ObjectProperties, KX_BoundBoxClass, KX_BoxBounds, and KX_CBounds

These were used in BL_CreatePhysicsObjectNew() in the converter. However, all
of the data put into KX_ObjectProperties was then copied again in
KX_ConvertBulletObject(). So, instead KX_ConvertBulletObject() now gathers the
information it needs itself, which avoid this odd double conversion step for
physics.

As a side-effect, the old code would result in static non-mesh objects with no bounds
set to still have triangle mesh bounds. This would result in no bounds for these objects.
If a bounds was set that required a mesh, non-mesh objects would become sphere bounds.
This is now true regardless of whether user bounds were set. In other words, static
non-mesh objects now use sphere bounds by default instead of mesh bounds. This might
slightly alter some games, but these objects should generally be set to No Collision
anyways.
