feat(tvix/eval): track source spans for `if` expressions r/4725
These are again a bit tricky in terms of emitted errors. The main error is that the condition is not a boolean, which means that the jump inspecting the condition must derive from the condition itself to return an error at the correct position. For other parts of the expression, it is simply the node itself.
