copies: extract an explicit `computechangesetcopie` method from context

Right now, the logic around changeset centric copies data are buried into the
"changectx" code. We extract this code in a dedicated method (in the copies
module) for clarity. This clarity will help to explicitly compute and caches
these data in the future.
