Levi Tamasi c0be6a4b90 Support allow_unprepared_value for multi-CF iterators (#13079) ... Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/13079 The patch adds support for the new read option `allow_unprepared_value` to the multi-column-family iterators `CoalescingIterator` and `AttributeGroupIterator`. When this option is set, these iterators populate their value (`value()` + `columns()` or `attribute_groups()`) in an on-demand fashion when `PrepareValue()` is called. Calling `PrepareValue()` on the child iterators is similarly deferred until `PrepareValue()` is called on the main iterator.
