lnwallet: add custom tlv blob to internal commitment struct

Browse Source 
In this commit, we also add the custom TLV blob to the internal commitment struct that we use within the in-memory commitment linked list.

This'll be useful to ensure that we're tracking the current blob for our in memory commitment for when we need to write it to disk.
