bcachefs: btree_path
This splits btree_iter into two components: btree_iter is now the externally visible componont, and it points to a btree_path which is now reference counted. This means we no longer have to clone iterators up front if they might be mutated - btree_path can be shared by multiple iterators, and cloned if an iterator would mutate a shared btree_path. This will help us use iterators more efficiently, as well as slimming down the main long lived state in btree_trans, and significantly cleans up the logic for iterator lifetimes.
