Test "other/nat-lit-add"

The kernel's Nat extension reduces Nat.add applied to two literals to a
literal, instead of unfolding the numerals to Nat.succ chains. The
arguments here are large enough that unfolding is not a practical
alternative, so a checker that only implements natLitEq-style
literal↔succ conversion will not get this for free.
Exported as natAddLit : Nat.add 123456789 987654321 = 1111111110 := rfl.
The application is Nat.add on .lits (not HAdd/OfNat).
