In this commit, we start to thread thru the new aux tap leaf structures to all relevant areas. This includes: commitment outputs, resolution creation, breach handling, and also HTLC scripts. Given the aux leaf store, and a struct that describes the current commitment, we can obtain the CommitAuxLeaves struct, then use that to derive the aux leaves for the commitment outputs and also HTLCs as well. When restoring commitments and pay descs from disk, we'll store the aux leaves as custom TLV blobs on disk, then use the aux leaf store to map back to the concrete aux leaves when needed.
