feat(tvix/eval): track source spans for `or` operator r/4723
This one is tricky, specifically the span used for the final jump. I
decided that it makes sense to use the attrpath node, as the final
jump is the one that jumps *over* the default value, so the effect of
this is more closely related to the selector than the default.

It might be more correct to pass through the `or` token itself and
point to this for the jumps, but it depends a bit on what shape of
errors we could end up producing from this.
