      Add a collection hashing function as outlined in WT-15382.

      In order to verify that two databases contain the same content, we've chosen to hash the database content. Rather than trying to load all keys/values into one big blob to hash, we should do it iteratively, as we scan content.

      One additional difficulty here is that test/format can use different forms of keys/values across tables. We may need to reuse the mirror table equality logic to account for this.
