test(tvix/eval): add eval-okay-closure-pointer-compare r/5310
This test case checks two things: * A sanity check that "pointer equality for functions" means not just the lambda, but also the upvalues. * To be pointer-equal, it is not enough for the upvalues to be normal-form equal (i.e. `nix_eq()`-equal); the upvalues must be *pointer*-equal. The second part of the test case checks for this.
