We currently treat page discards as a full page write of a tombstone, but we should instead treat it more like a delta write.

The Server team has requested that we set the LSNs for a tombstone write accordingly:

base_lsn = the LSN of the last full page
backlink_lsn = the LSN of the last page version

Note that this would require us to store base_lsn in the address cookie, so that this information would be available for fast truncate as explained in ~~WT-14960~~.
