pack-objects: use --objects-edge-aggressive for shallow repos
When fetching into or pushing from a shallow repository, we want to aggressively mark edges as uninteresting, since this decreases the pack size. However, aggressively marking edges can negatively affect performance on large non-shallow repositories with lots of refs. Teach pack-objects a --shallow option to indicate that we're pushing from or fetching into a shallow repository. Use --objects-edge-aggressive only for shallow repositories and otherwise use --objects-edge, which performs better in the general case. Update the callers to pass the --shallow option when they are dealing with a shallow repository.
