refactor(tvix/eval): remove extra Rc<..> around Value::Attrs r/5542
The `im::OrdMap` is already small and cheap to copy while sharing
memory, so this is not required anymore.

Only the `KV` variant may have slightly larger content, but in
practice this doesn't seem to make a difference when comparing the two
variants and this one is less complicated.
