btrfs: handle recording of zoned writes in the storage layer
Move the code that splits the ordered extents and records the physical location for them to the storage layer so that the higher level consumers don't have to care about physical block numbers at all. This will also allow to eventually remove accounting for the zone append write sizes in the upper layer with a little bit more block layer work.
