bcachefs: BTREE_ID_subvolume_children
Add a btree to record a parent -> child subvolume relationships,
according to the filesystem heirarchy.
The subvolume_children btree is a bitset btree: if a bit is set at pos
p, that means p.offset is a child of subvolume p.inode.
This will be used for efficiently listing subvolumes, as well as
recursive deletion.
