1. backupccl: enable restore_span.target_size …

   This setting was previously disabled because of timeouts being
   observed when restoring our TPCCInc fixtures. The cause of those
   timeouts has been identified as
   cockroachdb#88329 making it safe
   to re-enable merging of spans during restore. This settings prevents
   restore from over-splitting and leaving the cluster with a merge hangover
   post restore.
   
   Informs: cockroachdb#86470
   
   Release note (sql change): Sets `backup.restore_span.target_size`
   to default to 384 MiB so that restore merges upto that size of spans
   when reading from the backup before actually ingesting data. This should
   reduce the number of ranges created during restore and thereby reduce
   the merging of ranges that needs to occur post restore.
