Wait for one operation to succeed.
template< typename... T, typename U, typename Executor> awaitable< std::variant< T..., U >, Executor > operator||( awaitable< std::variant< T...>, Executor > t, awaitable< U, Executor > u);
If one operations succeeds, the other is cancelled as the OR-condition is already satisfied.
