fix(tvix/eval): `?` operator should use OpAttrsOrNotFound r/4544
Using `OpAttrSelect`, the ? operator will fail when encountering a
nested value that is not an attribute set.

This however breaks valid code, such as:

  { bs = 42; } ? bs.a.b

The fix is simply to use the same operator used in the `or` statement,
which leaves a sentinal on the stack if a field is not found or the
value is not an attribute set.
