feat: use lazy MessageData for omega errors (#4360) 
presumably this avoids unnecessary work when `omega` is used in tactic
combinators where the error message is never seen. Measurement did not
show
any significant changes, though.

With an artificial sleep in

I can observe that `omega` is slow and `try omega` fast, so it seems to
work at least.
