Switch to multi-inserts when registering dependencies for many code paths
This commit improves the dependency registrations by taking advantage of the preliminary work done in 63110c6, to group together the insertion of dependencies of the same type to pg_depend. With the current layer of routines available, and as only dependencies of the same type can be grouped, there are code paths still doing more than one multi-insert when it is necessary to register dependencies of multiple types (constraint and index creation are two cases doing that). While on it, this refactors some of the code to use ObjectAddressSet() when manipulating object addresses.
