fix(tvix/eval): remove impl PartialEq for Value r/5236
It isn't possible to implement PartialEq properly for Value, because any sensible implementation needs to force() thunks, which cannot be done without a `&mut VM`. The existing derive(PartialEq) has false negatives, which caused the bug which cl/7142 fixed. Fortunately that bug was easy to find, but a silent false negative deep within the bowels of nixpkgs could be a real nightmare to hunt down. Let's just remove the PartialEq impl for Value, and the other derive(PartialEq)'s that depend on it.
