feat(tvix/eval): remove Clone instance from Chunk and Lambda r/5142

Lambda has a quite large and variable-sized runtime representation,
unlike Rc<Lambda>.  It would be easy to accidentally call clone() on
this and create input-dependent performance regressions.

Nothing in the codebase is currently using Lambda.clone().  Let's
remove the derived instance.  If it's really needed it is very easy
to add it back in, but whoever does that will have to look at the
struct they're adding Clone to, which will hopefully prompt them to
think about whether or not that's really what they want to do.
