test(tvix/eval): add eval-okay-closure-pointer-compare

Browse source 
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.
