…ault value (#44982) This PR deprecates the `prefetch_batches` parameter of `Dataset.iter_rows` because it leaks an implementation detail (namely, that we use `Dataset.iter_batches` under-the-hood). This PR also increases the default value for 1) consistency with `iter_batches` and 2) to improve performance. For historical context, #43349 erroneously introduced the `prefetch_batches` parameter.
