bcachefs: BTREE_ID_snapshot_tree
This adds a new btree which gets us a persistent per-snapshot-tree
identifier.
- BTREE_ID_snapshot_trees
- KEY_TYPE_snapshot_tree
- bch_snapshot now has a field that points to a snapshot_tree
This is going to be used to designate one snapshot ID/subvolume out of a
given tree of snapshots as the "main" subvolume, so that we can do quota
accounting in that subvolume and not the rest.
