bcachefs: bcachefs_metadata_version_disk_accounting_inum
This adds another disk accounting counter to track usage per inode
number (any snapshot ID).
This will be used for a couple things:
- It'll give us a way to tell the user how much space a given file ista
consuming in all snapshots; i.e. how much extra space it's consuming
due to snapshot versioning.
- It counts number of extents and total size of extents (both in btree
keyspace sectors and actual disk usage), meaning it gives us average
extent size: that is, it'll let us cheaply find fragmented files that
should be defragmented.
